240 Zoological Society : — 



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 annnlata, described by myself in the ' Catalogue 

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

 KrefFt is identical with Pseudoelaps svjoerciliosvs, 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. Kubhigii, 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 

 Biemennia superciliosa. These, however, differ toto ccelo, as may 



be seen from the description given by myself (Colubr. Sn. p. 227), 

 and from the figures {antea, p. 1), where fig. a represents the 

 head-shields of Pseudonaia nuchalis, and fig. b those of Diemennia 

 superciliosa. 



The synonymy of this species, therefore, would be : — 



Diemennia superciliosa.
