These spocimons were sent to me as J{. tuhcrciilntn (Anderson). In my 

 monograph already reforrod to, 1 tried to show that this "species " (at that 

 time resting on a sohtary specimen in the Indian Museum, the "type" 

 whioii I had examined) was not entitled to rank as a species apart from 

 ci/fntdciiictus (Daudin). I consider these thirteen Siam specimens are fi/(rn<>- 

 cinctii.^ (Daudin) for the following reasons : (1) Because the numbers of the 

 costal rows accords with the range given in Boulenger's description in his 

 Catalogue (Vol. Ill, p. 205) (2) These costals have tubercles bituberculate 

 in character, and exactly like those seen in Indian specimens of ci/anocinctus, 

 (figured in No. 8C). (3) The range of ventrals is well within that given 

 by Boulenger. (4) There is nothing in the lepidosis of the head by which 

 they can be considered distinct, (o) A critical examination of the skulls 

 of Nos. 9 and 13, bone for bone, beside two skulls in my collection from 

 Indian examples, show no differences that I can discover. (0) The denti- 

 tion agrees with that of my Indian specimens, and is as follows — The post 

 maxillary teeth vary from 7 to 10 (Indian specimens 6 to 10) ; the palatine 

 are 7 (Indian specimens 7 to 0) ; the pherygoid J 7 to 24 (Indian specimens 

 15 to 18) ; mandibular 17 (Indian specimens 16). (7) Further the gravid 

 Siam specimen measured 2 feet 9 inches, and I have examined a gravid 

 female of cifanocinctus (Daudin) in the Indian Museum 2 feet 1 1 inches 

 in length. (8) The colouration is, as 1 have remarked it, in Indian 

 specimens.
