heheticus— T. palmatus ; and two of the latter, S. maculosa and S. atra. He 
treats of their propagation, development, of the histology of the skin, the skull, 
and dentition (which is not uniserial). A great part of the paper is devoted 
to a review of the literature as far as it is known to the author. The paper 
is illustrated by three plates (pi. 4 representing T. tceniatus and heheticus') j 
and ought to he studied by all interested in the study of tailed Batrachians. 
[The author is wrong in denying the fact that the ribs of adult Pleurodeles 
perforate the integuments.] 
Chioglossa lusitanica. I)r. Bonnaret has found an example, which he de- 
scribes and figures in Arch. Oosmolog. 1867, p. 99, pi. 6. 
Phthodon persimilis. Mr. St. G. Mivart has shown that this Newt has no 
sphenoid teeth, and therefore is the type of a distinct genus, Pectoglossa, more 
nearly allied to Onychodactylus than to Plethodon. It is from the Laos 
Mountains. Proc. Zool. Soc. 1867, pp. 695-699. 
Plethodon intermedins and croceater, spp. nn., Cope, Proc. Ac. Nat. Sc. Phi- 
lad. 1867, pp. 209, 210, from the Pacific coast of North America. 
Amblystoma. Mr. Cope treats of the character of this genus, 
which by itself 'forms the family Amblystomidm \ from the im- 
mense collection preserved in the Smithsonian Institution he 
gives detailed descriptions of nineteen species, seven of which 
are new. Proc. Ac. Nat. Sc. Philad. 1867, pp. 166-211. He 
pays much attention to the various changes during the meta- 
morphosis of each species. The Axolotls are not included. 
M. Dumertl continues his observations on the development 
of the Axolotl. He shows by experiments that the external 
gills are most easily reproduced when lost, and that their remo- 
val does not in any way affect their respiration. Three exam- 
f )les out of nine deprived of their branchiae passed from the 
arval to the perfect state. Ann. Sc. Nat. 1867, vii. pp. 229- 
254 \ Compt. Rend. 1867, August 5, pp. 242-246, translated in 
Ann. & Mag. Nat. Hist. xx. 446-449. 
M. Dumeril devotes also a separate memoir to monstrosities (chiefly of 
the limbs) observed among the young examples bred in Paris. Nouv; Arch.

M. J. M. Philipeaux (Ann. Sc. Nat. 1867, vii. p. 228 ; Oompt. Rend. 1867, 
June 10, p. 1204 ; Ann. & Mag. Nat. Hist. xx. p. 149) describes experiments 
on the reproduction of limbs made on Axolotls^ with exactly the same results 
as those obtained on Tritons (see Zool. Record, iii. p. 130). 
Menohranchus. On the blood-corpuscles, see Van der Hoeven, in Arch. 
Neerland. 1867, p. 288. 
Proteus. Mr. Cope has examined some skeletons in Hyrtl’s collection, and 
distinguishes five species, viz. zoisii, carrarcep xanthostictus, schreihersii, and 
anguinus. Journ. Ac. Nat. Sc. Philad. v. pp. 103, 104.
