pl. xviii. figs. 2& 2a. China. 
24, ACHALINUS RUFESCENS. Hongkong.—TI obtained four 
specimens in Hongkong Island, found in the low vegetation on 
the slopes of the Peak. In one specimen both anterior temporals 
touch the eye on both sides. Scales somewhat irregular, 23-25 
in mid-body. Ventrals and subcaudals 150 +56, 158+58, 158+ 
61, 154+58. Colour uniform olive-brown above, slightly darker 
vertebrally, and with iridescence in reflected light. Head same 
colour above, merging to chestnut on temporal regions. 
25. ACHALINUS BRACCONIERI. SS. China.—I think that this 
species will have to be united with dA. spimalis; the differences 
between the two shown by Mr. Boulenger' are considerable but 
not constant, being shared by individuals of both supposed species. 
For instance, in all the four specimens of A. spinalis that I have 
examined (one of which I presented to the British Museum, 
which has been seen and identified as such by Mr. Boulenger) 
the scales are 23, and not 21. The relative length of the sutures 
between the internasal and prefrontal has, in my opinion, little 
or no weight. The specimen of A. spinalis I sent to the British 
Museum has the internasal suture about two-thirds the length of 
the prefrontal; and in more than one specimen of bracconiert in 
the British Museum a similar condition exists. The specimen 
figured by Stejneger* from Japan which he calls spinalis is more 
like Mr. Boulenger’s bracconieri, but has 23 scales. 
26. ACHALINUS SPINALIS. China, Japan.—I saw three speci- 
mens in Mr. Owston’s collection from Mount Fuji, Japan, and 
one I found in the Siccawei Collection. In all there is a large 
shield on the postero-lateral region of the parietals similar to 
those described under A. bracconiert, and, ike them, separated by 
one scale in the median line. Ventrals and subcaudals 154+ 58, 
165+44, 165448, 1704 44. 
27. Lycopon Aauticus. Southern Asia from India to Malay 
Archipelago, Philippines, Formosa (City Hall Mus.), Hongkong ? 
(Boettger *), 8. China ? viz. from Amoy (Steindachner *). 
28. Lycopon Fascianus. W. Yunnan (Anderson), Assam, 
Burma. 
29. Lycopon suscincrus. Malay Peninsula and Archipelago, 
Sumatra, Borneo, Java, Timor, Hongkong, Philippines.—There 
are two specimens in the City Hall Museum from Hongkong and 
one from Timor. I also examined a fourth, which Mr, Armstrong

species in that Institution is from Formosa.
