saying that there are fourteen primary tubercles. Nor can 

 the great difference between the species in the number of the 

 secondary tubercles be looked upon as any thing else than a 

 mark of specific distinction. A specimen of E. cliloroticus of 

 the same size as the larger of the two specimens of E. rari- 

 tuherculatus has the poriferous zone at the ambitus 3 millim. 

 wide.

LIV. — 071 a rare Himalayan Toad^ Cophophryne sikkim- 

 ensis, Blyth. By G. A. Boulenger. 



Mr. W. T, Blanford has just presented to the British 

 Museum three specimens (a male, a female, and a young) of 

 a very rare Batrachian described by Blyth in 1854 under the 

 name of Bomhinator sikkimensis. The two original speci- 

 mens were obtained in Sikkim by Captain Sherwill and are 

 preserved in the Calcutta Museum. A third specimen, 

 received by the same institution, and noticed by Anderson in 

 1871, was procured on the Sengalula range, Darjeeiing, at 

 an altitude of 12,000 feet. The three specimens now added 

 to the British-Museum collection were collected by Mr. Blan- 

 ford at Byutan, foot of Yakla Pass, Sikkim, at an altitude of 

 13,000 feet. 



I know of no other preserved specimens. The late F. 

 Stoliczka stated *, it is true, that he obtained a few speci- 

 mens around Darjeeiing at an elevation of about 7000 feet. 

 But on comparing his description with the material now to 

 hand, I come to the conclusion that he mistook the young 

 Bufo Mmalayanus for the B. sikkimensis. The reference to 

 Stoliczka's Bufo sikkimensis and to the abstract I have given 

 of it in the ' Catalogue of Batrachians ' (p. 305) should there- 

 fore be transferred to the synonymy of Bufo Mmalayanus^ 

 Gthr. 



Now as to the systematic position of this Batrachian. 

 Theobald recognized it as belonging to the family Bufonidse, 

 and created for it a new genus, which he named Scutiger^ 

 assuming apparently the nuptial excrescences of the male to 

 be a permanent character ; in addition to the latter character
