some Species of Palamneeus. 39 
spinifer in the number of the pectinal teeth, and I have little 
doubt the two are synonymous. 
But to complicate the matter still further Dr. Thorell subse- 
quently referred to P. Petersti a number of specimens obtained 
by Sig. Fea and Comotto in Burma, which specimens had 
been previously identified by Mons. Simon as P. bengalensis 
(C. Koch). But both these identifications are, I think, erro- 
neous ; for, in the first place, bengalensis of C. Koch is a true 
Scorpio, as is shown by examples in this Museum, and, in 
the second place, the Burmese specimens above referred to 
seem to be different from the type of Petersi? that Thorell 
described from Singapore. 
The first assertion needs no justification; the second is 
based upon the following facts. 
Whilst collecting in various parts of Burma Mr. E. W. 
Oates obtained literally many hundred examples of a species 
of Palamneus, which is undoubtedly the Burmese form that 
Dr. Thorell identified as P. Peters. But amongst those 
collected at Rangoon there are three examples which are at 
once to be recognized from the rest. ‘These are of larger size, 
with the inner border of the hand beset with spiniform 
tubercles ; the vesicle is clear ferruginous, and the chele or 
palpi of the male have almost the same form as in the female. 
In the others, on the contrary, the size is smaller, the inner 
border of the hand is thickly granular and not spicular, the 
vesicle is generally of about the same tint, though sometimes 
a little paler than the rest of the tail, and the chelz of the 
male are more slender and longer than in the female, the 
manus being especially narrow. Of this latter kind the 
British Museum has those quantities of specimens that were 
generously presented by Mr. Oates, and, in addition, one 
example obtained by Sig. Comotto at Minhla—an example, 
by the way, that was kindly given to the Museum by the 
Marquis G. Doria, and which is one of those above referred 
to as having been identified as Petersiz by Dr. Thorell. But 
of the former kind, in addition to those just mentioned from 
Rangoon, the Museum has very many examples from India, 
East Indies, Bengal, Mergui, Perak, Penang, Singapore, and 
Billiton Island. This species is, I think, spdnifer (Ehrb.) 
and Petersdi of 'Thorell. 
There is nothing in Ehrenberg’s figure and description to 
refute this view. On the contrary, it is clearly shown that 
the inner border of the hand is armed with spiniform tubercles 
and that the vesicle is ferruginous. The specimen, moreover, 
came from India, whence this Museum also has examples. 
Furthermore, the Museum, as already stated, has specimens
