3. Note on Diemennia superciliosa. By Dr. A. Gunther. 



The Proceedings of this Society of last year* contain a very inter- 

 esting observation of Mr. Krefft, of Sydney, according to which a 

 small banded Snake, which he identifies with Furina textilis, Dum. 

 & Bibr., is merely the young of a very large species, the adult of 

 which is of a nearly uniform coloration. Mr. Krefft (who, for the 

 benefit of the collection entrusted to his care, is very anxious to have 

 his specimens identified with the types contained in European col- 

 lections) has sent us an old and two young examples of this Snake ; 

 and having re-examined the species of Diemennia and the literature 

 referring to them, I am enabled to settle some points on which doubts 

 have been entertained. 



The young specimens, then, found by Mr. Krefft do not belong 

 to Furina textilis, Dum. & Bibr., which has three posterior oculars, 

 but to Diemennia annulata, described by myself in the ' Catalogue 

 of Colubrine Snakes,' p. 213; and the old individual sent by Mr. 

 Krefft is identical with Pseudoelaps super ciliosus, Fisch. M. Jan, 

 of Milan (who says that he has examined the Snakes of the Hamburg 

 Museum), describes the adult Snake under two names, Pseudoelaps 

 sordellii and Ps. kubingii, the latter being founded on an accidental 

 variety, in which some of the head-shields are confluent. 



Mr. Krefft, in a letter addressed to me, alludes to Pseudonaia 

 nuchalis as a species which, perhaps, might be identical with an old 

 Diemennia superciliosa. These, however, differ toto coelo, as may
