Diagnostic characters , — Similar to Acanthion bmchywnim , but 
apparently slightly smaller; with less conspicuous throat collars. 
Color.— As in A. hrachyurum, but in the single available specimen 
the light throat collar very poorly defined and the sides of body 
are lighter in color, owing to the spines having lighter bases than in 
A. Irracht/tirum. 
SkulL — Evidently smaller than that of A* * hr&ckyurvnn , Jentink a 
gives the total length of the skull of an old male as 135 mm. The 
skull of a young male in the IT. S. National Museum measures 103 mm. 
total length, against 110 mm. total length in a skull of the same age, as 
judged by the teeth, from the Malay Peninsula. 
Meamremen is, — See table, page 503. 
Specimens examined. — One, a young male, from Aru Bay, Sumatra. 
Remarks* —Jentink* records Acanthion m ulleri and Acanthion javar 
nicum from Sumatra, Tanjong Morawa. No description of them is 
given, but it is to be supposed that they differ, as pointed out by 
Jentink" in 1870, mainly in size—in which case there are two distinct 
forms of Acanthion in Sumatra, That Jentink did not have a speci¬ 
men of Thecwrus, is evident from the fact that the smaller of his 
species, A . javanicum , has a skull length of 118 him., while the skull 
length of Thecurus is scarcely more than 100 mm.
