REPTILIA AND BATRACHIA. 
VlPERID^. 
In a paper entitled, “ !^tudes sur les Viperes du groupe ammodytes — 
aspis — berus,’^ A. Tourneville describes with great details Vij)era berus 
seoanii, Lataste, and V. latastiij BoscA, and compares these forms with 
the other European Yipers. A variety of V. berus seoanii and the heads 
of the other species, figured. Bull. Soc. Z. Fr, 1881, pp. 38-72, pi. i. 
Rhinocerophis nasus, sp. n., Garman, Bull. Mus. C. Z. viii. p. 80, Eastern

BATRAOHIA. 
Parker, W. K. On the Structure and Development of the Skull in the 
Batrachia. Pt. iii. Phil. Tr. clxxii. pp. 1-266, pis. i.-44. 
The skulls of 73 species of Ecaudata are figured and described, some 
in the larval as well as the perfect state ; these skulls are compared with 
that of Rana temporaria^ taken as the “ norma ” or pattern form. The 
author also makes remarks on the likeness and unlikeness of the skulls 
of the Caudata and Ecaudata.

Pp. 151-213 and pis. xxv.-xxxv. refer to the Batrachia. 
ECAUDATA. 
P. Brocchi (Miss. Sc. Mex. iii. 2, Batr.) criticises the classifications of 
Dumdril, Gunther, Cope, and Mivart, and proposes the following arrange- 
ment:— 
I. Tongue distinct {Phaneroglossa), 
A. Teeth in the upper jaw. 
Fingers not dilated Raniformes. 
Fingers dilated Hylmformes \_Hyli-']. 
B. Teeth in both jaws Hemiphractiformes. 
c. Teeth none. 
Sacral vertebra dilated Bufoniformes. 
Sacral vertebra not dilated Hylaplesiformes. 
II. Tongue not distinct (Phrynaglossa s. Aglossa). 
Teeth in the upper jaw Dactylethriformes. 
Teeth none Pipceformes ^Pipi-']. 
Boulenger, G. a. Sur les larves des genres Pipa et Dactylethra. Bull. 
Soc. Z. Fr. 1881, pp. 27-29. 
Contrary to what has been suspected by Lataste [see Zool. Rec. xvi. 
Rept. p. 14], the larvae of the Aglossa are provided with two spiracula or 
opercular slits, and are therefore not Mediogyrines.
