2232 Reptiles. 



The T. palmipes has been found in the Department de la Moselle by Fournel, by 

 Sturm in Germany, by Razoumowsky in Switzerland, by Latreille, &c, in France, by 

 De Selys, Von Haesendonck and myself in Belgium. Prince Charles Bonaparte's 

 thinking it may be a variety of T. punctatus, makes me believe that the species is un- 

 known in Italy. 



I have kept this newt for more than six months in a glass bowl, feeding it with 

 flies and small earth-worms. 



The species of Triton as yet discovered in Belgium are the following : 



1. T. cristatus, Latr. — Lacert. palustris, Linn. Molge palustris, Merrem. 



2. T. alpestris, Laur. Syn. — S. cincta, Latr. S. Wurfbani, Laur. Rubriven- 



tris, Daud. 



3. T. punctatus, Daud. Syn. — S. elegans, Daud. Lacert. vulgaris and aquatica, 



Linn. 



4. T. palmipes, Daud. 



The T. cristatus and alpestris are very distinct. The T. punctatus and palmipes, 

 especially the females, are more difficult to distinguish; but the males during the 

 spring months are very different, as the following characters will show. 



Triton punctatus. Triton palmipes. 



1. Tail gradually tapering to a point. 1. Tail suddenly truncate before the apex, 



and terminating in a slender filament 

 3 lines in length. 



2. Hind feet having the toes free, only 2. Hind feet perfectly palmate, all the 



edged by a membrane. toes united by a membrane. 



3. Back with a very large, festooned, un- 3. Back flattened, with two elevated late- 



dulating crest, which extends from ral lines passing above the eyes and 



the nape of the head to the end of extending to the base of the tail, 



the tail. No lateral elevated ridges. The dorsal crest small and simple. 



4. Length much greater than palmipes. 4. Size much smaller than punctatus. 



I have penned this short note because I believe that facts relating to the geographi- 

 cal distribution of British animals on the Continent may be agreeable to some of the 

 readers of the ' Zoologist.'

Crag Mollusca.* 



I have ever upheld the publication of monographs as a great and lasting boon to 

 Natural History. However limited the subject, we glean from a monograph all that 

 is known respecting it : hence a monograph may be compared to a lens that collects
