Taruffi C. 1881–94. Storia della Teratologia [History of Teratology]. Bologna [Italian].
See specific volumes below.
Taruffi C. 1881. Storia della Teratologia I [History of Teratology I]. 371 pp. Bologna [Italian].
Congenital – Teratologic cases through time, anecdotal, and scientific, from antiquity to this day – including those mentioned in many mythologies (among them Indian, Egyptian, Nubian, Greek). A good example are the Gorgons of Greek myth, which had reptile features including snakes for hair. He also provides a historic overview and explains how newborn human frog-resembling monsters had been believed to result from hybridization until the mid eighteenth century.
He discussed theories on the lack of certain teratologies in batrachians (Baer 1828; Dareste 1877; Saint-Hilaire 1837).
Taruffi C. 1882. Storia della Teratologia II [History of Teratology II]. 578 pp. Bologna [Italian].
Congenital – Theories on the origins of teratologies (Bruch 1867) and the merits of true double monster and hyper-regenerational causes of teratologies in batrachians.
Dicephalic ophidians survive longer than saurians.
Stated that true posterior body duplicity (a common teratology in mammals) had not been observed in reptiles, despite Tiedmann (1831) and Wiese (1812) having reported to have observed it in lizards.
Trauma – Bifid double tails are found in ofidians, saurians, and batrachians, citing Ambrosini as published in Aldrovandi (1642).
Pseudopathology – Reported that Aldrovandi (1642) received a donation of a live lizard that had two heads, with one being in place of the tail. This account was not only published by Aldrovandi (1642; p. 659, figs. V, VI), but also independently by Beltrami and Rigal (1831) and by Torquato Bembo of Padova, son of Cardinal Bembo (no publication year or title were provided).
Taruffi C. 1885. Storia della Teratologia III [History of Teratology III]. 589 pp. Bologna [Italian].
Congenital – Review of the different types of teratology and noted how many animal cases were known of each. He remarked that of 24 cases of pleuromely (thoracomely) animals known, batrachians accounted for nearly half (11 in total) as also noted by Van Deen (1838), Van der Hoven (1840), Balsamo-Crivelli (1865), Ercolani (1882, 2 cases), Fabretti (1875) and Parona (no date given), Alessandrini (1854), and Strobel (1876).
Corrects last volume, relating Braun’s report of a dicephalic Salamandra maculosa and Born’s of a dicephalic Rana fusca.
Supernumerary limb in Rana (Ercolani 1882), noting one attached to the abdomen (gastromelia) and citing 11 cases of pleuromely and 9 cases of ileopolymely in Rana (Balsamo-Crivelli 1865; Duméril 1865; Fabretti 1875; Lunel 1868; Otto 1816, 1841; Strobel 1876 and Parona).
Femoral duplication was very rare in Rana (Otto 1816), Triton (Camerano 1882), and axolotl (in which humeral duplication also occurred) (Sordelli 1882).
Polymelia in Rana (Bassi 1874; Cavanna 1879; Gervais 1864).
Claimed polydactyly in urodels is acquired, not congenital and that new digits can be added (hyperregeneration), as shown by Siebold (1828), Duméril (1865), and Sordelli (1882).
Duplication of the foot in a single leg is rare; the only case known to him, Ercolani’s (1882) Rana esculenta.
Trauma – Claimed polydactyly in urodels is acquired, not congenital and that new digits can be added (hyperregeneration), as shown by Siebold (1828), Duméril (1865), and Sordelli (1882).
Taruffi C. 1886. Storia della Teratologia IV [History of Teratology IV]. 534 pp. Bologna [Italian].
Congenital – Reviewed anecdotal reports of anomalous snakes (e.g., Giulio Capitolino).
Reviewed Aristotle’s “De generatione animalium” book IV, mentioning his explanation for the occurrence of a dicephalic snake.
Dicephalic lizards (Bibron cited by Saint-Hilaire 1836) and snakes (Aristotle, Aelianus, Aldrovandi 1642; Dutrochet 1829; Edwards 1751; Lacépède 1789; Lowne 1872; Porta, Lanzoni 1690; Redi 1684; Valentin 1704).
Double-faced reptiles and amphibians by [Catesby (as reviewed by Edwards 1754), Sack (1831) and Born (1881), but incorrectly cited and not found].
Supernumerary and abnormal limbs in frogs (Balsamo-Crivelli 1865; Bassi 1874; Cavanna 1877, 1879; Cisternas 1865; D’Alton 1853; Duméril 1865, Ercolani 1882; Fabretti 1875, Gervais 1864; Lunel 1869; Otto 1816, 1841; Parona 1883; Sordelli 1877, 1878; Strobel 1876; Van Deen 1838; Van der Hoeven 1840; Vallisneri 1706, and Thomas, as cited by Duméril (1865)).

Congenital – Correction to tome III, cites pleuromely in Rana (Mazza 1888) and axolotl (Sordelli 1882).
Polymelia in Rana (Sordelli 1876; Strobel 1876), but Fauvelle’s 1886 interpretation of hyperdactyly makes doubtful that the cause of polymely in the axolotl reported by Sordelli (1883) is congenital.
Trauma – Correction to tome IV, cites Otto (1816) as having observed multiple-tailed lizards.
Fauvelle’s 1886 interpretation of hyperdactyly makes doubtful that the cause of polymely in the axolotl reported by Sordelli (1883) is congenital.

Taylor JA. 1984. Ecology of the lizard, Ctenotus taeniolatus. Interaction of life history, energy storage and tail autotomy. PHD Thesis, University of New England, Armidale, Australia.
Trauma – Ctenotus taeniolatus has no abdominal fat bodies, so stores majority of lipids in the tail. Survival at 5°C or 10°C was for 66 days without tail, contrasted with more than 90 days for intact individuals. Autotomy levels of 40–70% was somewhat age related, similar numbers to those observed in Hemiergis decresiensis (Robertson 1981). Frequencies were high in species with abdominal fat bodies (Lampropholis delicata and Leiolopisma platynota). Starved or cold geckos retain their tails for a longer period (Daniels 1981).
Increased mortality over winter in Lacerta vivipara with partially regenerated tails (Bauwens 1981).
Removal of tail in Hemiergis peronii results in smaller clutch size (Smyth 1974).
