462 Mr. G. A. Boulenger on Lycodon atropurpureus 



OgdocontAj gen. nov. 



Differs from Telesilla in its shorter primaries, with costal 

 margin more decidedly arched towards apex, the subcostal 

 furca, formed by the third and fourth branches, considerably 

 longer ; the rudiment of the discocellular veinlet of secon- 

 daries almost entirely obliterated ; middle tibia decidedly 

 shorter instead of longer than the femur, the interior spur 

 longer, tarsus much more slender and longer ; posterior legs 

 longer and with longer tibial spurs ; labial palpi with slightly 

 longer terminal joint ; abdomen less strongly tufted. Type 

 P. cinereola. 



The generic name is suggested by the markings on the 

 primaries of 0. cinereola. 



The Japanese u Miana" segregata, Butler (Ann. & Mag. 

 Nat. Hist. ser. 5, vol. i. p. 85, and 111. Typ. Lep. Het. ii. 

 p. 25, pi. xxix. tig. 5), is a Telesilla. 



I have been unable to identify Bremer's Placodes fusco- 

 maculata from North China ; it may be not even allied to 

 Telesilla. 



LIII. — Note on Lycodon atropurpureus, Cantor, and 

 Bufo stomaticus, Lutken. By G. A. Boulenger. 



PROFESSOR Lutken has very kindly sent me for examination 

 examples of a Lycodon and of a toad from India preserved in 

 the Zoological Museum of Copenhagen, and which were 

 obtained by the late Mr. G. Westermann, the discoverer of 

 one of the most remarkable of Indian snakes, Elachistodon 

 Wester manni, lieinh. The exact locality where these speci- 

 mens were procured is not known, but they are believed to 

 be from Assam ; they are perhaps from Bengal, like the 

 Elachistodon. The Lycodon had been provisionally named 

 by Prof. Lutken many years ago L. subfuscus, Cantor; and it 

 is indeed very probable, from the number of ventral and 

 caudal shields, that this determination is correct. On the 

 other hand, it is equally probable that it represents the L. 

 airqpurpurew of the same author, and I have described it 

 below under that name. The toads were described by 

 Prof. Lutken himself as Bufo stomaticus in 1862; but as the 

 locality whence they were procured was not indicated in the 

 original description, no mention of that species is made in my 

 ' Reptiles of India.' Bufo stomaticus is, however, a distinct 

 species, allied to B. Andersonii, from which it differs in the 

 absence of a tarsal fold.
