344 Mr. G. A. Boulenger on the 



pace Forbes, no reference to the species, not diminished by 

 foreign writers ; de Blainville's synonymy is most confusing, 

 Agassiz was clearly in doubt as to what was A. scutatum and 

 what A. verrucosum. 



Miiller and Troschel do not appear to have been satisfied 

 with Forbes's description of "^. scutatum,''' and there can be 

 no doubt that much confusion would result if that specific 

 name were to be used ; the term with which it is most often 

 confounded is verrucosum, and that goes now that we know 

 that it is synonymous with the cajmt-medusce of Linnaeus. 

 Scutatum, then, should not usurp the place long occupied by 

 the specific name given by Miiller and Troschel.

XLV. — Bemarl's on the Genus Ileterolepis, Smith. 

 By Ct. a. Boulenger. 



Aetiiougii specimens of the West-African Heterolepis 2'>oensis 

 have been frequently received during the forty years that have 

 elapsed since the establishment, by AndrewSmith, of this curious 

 genus of Snakes, the type species, //. capensis, remained one 

 of the British j\Iuscuni's most important desiderata. I was 

 therefore extremely pleased to receive a few days ago, through 

 the kindness of Mr. Trimen and Mr. I'eringuey, of tlie South- 

 African Museum, a specimen from Delagoa Bay, consisting 

 of the head and anterior part of the body and the tail, of what 

 ] take to be the long-desired //. capensis. 



Til is specimen agrees so well with Pcters's //. Gucinzii, 

 from Fort Natal, that I entertain no doubt as to the identity 

 of the two. U lie late Prof. Peters felt in fact very doubtful 

 as to iho pvoj)riety of separating //. (ri;cin~ii I'vom If. capensis,
