CRUSTACEA OF THE MERGUI ARCHIPELAGO. 225 
Family PaguripEa. 
Genus Pacurus, Dana. 
128. Pagurus PUNCTULATUS, Oliv. 
Pagurus punctulatus, Milne-Edwards, Hist. Nat. des Crustacés, t. i. 
p. 222. 
Pagurus punctulatus, Miers, Voyage of H.M.S. ‘ Alert,’ 1884, p. 555. 
One specimen was collected in Elphinstone Island Bay, and a 
smaller one at Owen Island. 
In these specimens the eye-peduncles are nearly as long as 
the anterior margin of the carapace, whereas Milne-Edwards 
describes the eye-peduncles as being “‘ beaucoup moins long” 
than that margin. I am disposed therefore to regard his descrip- 
tion as inexact, because these specimens in their other details 
agree perfectly with the description in the ‘ Histoire Naturelle 
des Crustacés.’ The eye-peduncles surpass the peduncle of the 
outer antenne by the length of the cornea, and they are a little 
shorter than the peduncle of the inner antenne. 
Pagurus punctulatus has been recorded from nearly the whole 
Indo-Pacific region, from the Red Sea and Madagascar to 
Australia and the Sandwich Islands. 
129. Pagurus DEFoRMIs, J/.-Hdw. 
Pagurus deformis, Milne-Edwards, Hist. Nat. des Crustacés, t. ii. 
p. 222; Hilgendorf, Monatsber. Berliner Akademie, Nov. 1878, p. 818. 
One female specimen, inhabiting the shell of a Turbo, was 
found at Owen Island. 
Pagurus deformis has been recorded from the coast of Mozam- 
bique (Hilgendorf), the Mauritius and the Seychelles (Milne- 
Edwards), Timor, Amboina, the Anachoretes, New Ireland 
(Hilgendorf), and the island of Oushima, Japan (Stimpson). 
It is a little doubtful whether the specimen collected at Tahiti ‘ 
and described by Heller (Crustaceen der Novara-Reise, p. 86) 
really belongs to this species, because Heller describes the ter- 
minal joint of the third pair of ambulatory legs as being twice 
as.long as the penultimate, whereas in the true P. deformas the 
terminal joint does not attain that length.
