described and figured as that of an adult Onychodactylus (? species), 
belongs to the larva of Onychodactylus japonicus. — Pec.]

Tr. Z. S. xi. pp. 171-214, pis. xxxvi.-xli.

L. Camerano describes a case of polymely in Molge vulgaris ; Atti 
Soc. Ital. xxv. pp. 113-116, woodcuts. 
Molge, Merrem. This name is substituted for Triton , Laur., pre-

and hagenmuelleri (Lataste), pp. 357-359 ; Zool. Anz. v. 
Molge montana (Savi). The same writer points out the absence of a 
bony fronto-squamosal arch, and the peculiar structure of the tongue in 
this species, and proposes to maintain the genus Megapterna , Savi ; l. c. 
pp. 45 & 46. 
Diemyctylus miniatus meridionalis , subsp. n., Cope, Bull. U. S. Nat.

by Carbonnier, P. U. S. Nat. Mus. v. pp. 221 & 222. 
J. W. Spengel makes remarks on the Axolotl, with special reference 
to Velasco’s paper [cf. Zool. Rec. xvi. Rept. p. 18]. The question is no 
longer under what circumstances transformation takes place, but what 
circumstances prevent the transformation of the Axolotl into Ambly- 
stoma ; Biol. Centralbl. ii. pp. 80-83.
