156 A Memoir on the living Asiatic Species of Rhinoceros. [No. 2, 
examination, besides the figures referred to. Strange to say, we clo 
not yet possess a single * spoil’ of this species in the museum of the 
Society ! But I trust and have reason to believe that this singular 
hiatus in our series will speedily become a record of the past. 
Plate I, fig. 2, represents the broad type of skull of Rh. sohdai- 
cus, from the Bengal Sundarb&ns ; and pi. XI, f. 2, the same from 
the Tenasserim provinces. PI. I, f, 3, and pi. II, f. 3, represent an 
aged specimen of the narrow type of sonjoaicus, from Jam. We 
have Tenasserim examples quite similar, except that they are not so 
aged; but I figure the Javanese one, that there should be no mis¬ 
apprehension about the identification of the species. I have already 
remarked that these comparatively broad and narrow types complete¬ 
ly grade into each other, as likewise in the preceding species. It is 
simply impossible to trace a dividing line in the instance of either 
one of the three. 
Plate III, fs. 1, 2, represent the corresponding types of males of 
the two-horned Rh. sitmatranus- ; f. 3, of a female, of which the 
stuffed skin of the head is also in the Society’s museum. All are 
Jrom the Tenasserim provinces. 
Plate IV, f. 1, is from a drawing which I took of a beautiful spe¬ 
cimen in the possession of Lt.-Col. Fytche,. Commissioner of the 
Martaban and Tenasserim provinces, at Moulmein. # The animal was 
killed in Tavoy province, near the frontier of Siam. When I first 
saw this specimen, the horns were attached to the skin; and they 
now fit to the rugosities of the bony surface. The resemblance of 
the anterior horn (more especially) to the extraordinarily fine horn 
figured as that of a new species, Rh. Crossii, Gray (in the Proa. 
Zool. Soc. 1845, p. 250, and copied in pi. IV, f. 4), induced me to con¬ 
jecture that the latter was merely a magnificently developed specimen 
of the anterior horn of Rh. Sumatra hus ; but the difference of size 
(that of Rh. Crossii measuring 2 ft. in span of curvature from base 
to tip) seems to be too great. Of the near affinity, however, there 
can be no doubt; and it is just such a horn as the nearly akin 
(however huge) Rh. plattriiinus of Cautley and Falconer, from 
the Siwalik deposits, might have borne.t Other kindred fossil species 
* The horns, as represented in the lithograph, are not sufficiently massive. 
f In a letter just received from Col. Fytche, who had recently returned from 
a tour in the southern Tenasserim provinces, that officer writes—“ I came across
