this species, which has only one congener, viz. Brachysoma 

 triste—Glyphodon tristis, Gthr. 



Furina bimaculata. 

 Furina bimaculata, Dum. & Bib. p. 1240. 

 Brachysoma diadema, Gthr. Colubr. Snakes, p. 229 (not Schleg., Fitz.). 



This is the type of a distinct genus, for which I had formerly 

 adopted the name of Brachysoma, but for which that of Furina 

 is better retained. It is readily distinguished by its protruding 

 rostral shield. The species is a native of Western Australia. 



Diemansia cucullata. 



Giinth. Ann. & Mag. Nat. Hist. 1862, p. 52. 



Mr. Krefft has sent two other specimens of this species ; they 

 have the scales in fifteen rows. 



Diemansia annulata. 



Giinth., Colubr. Snakes, p. 213. 



This is the snake which Mr. Krefft has recognized as the 

 young of a very large species, and to which he has applied the 

 name of Furina textilis*. Both species, however, are distinct, and 

 may be readily distinguished by the number of the postorbitals, 

 which is two in four examples of D. annulata examined by my- 

 self, whilst Furina textilis has three of those shields. Mr. Krefft 

 has sent a stuffed example, 6 feet long, in which the dark cross 

 bands have nearly entirely disappeared. This species has not 

 the large rostral shield of Pseudonaja nuchalis. 



Fam. Elapidae. 

 Neelaps. 



No other teeth behind the fang. Scales smooth, polished, 

 without a groove at the apex, of equal size, in fifteen rows, 

 llostral shield large, broad, depressed, rounded behind; nasal 

 single, long, replacing the loreal. Two postoculars, the upper 

 sometimes confluent with the superciliary. Ornamental colours 

 arranged in longitudinal bands. 



Central America. 



Neelaps calonotus. 

 Furina calonotus, Dum. Bibr. Erpet. Gener. vii. p. 1241, pi. 75 {bis). 



This snake has been described and figured in the work quoted, 

 where it is said to be a native of Tasmania. However, we have 

 received a specimen from Baranquilla, at the mouth of the River 

 Magdalena, in New Granada, with the same collection which 

 contained the genus Brachyurophis, described above. It must
