270 Mr. KE. J. Miers on Crustacea from 
as long as the carapace; fourth to sixth joints not much di- 
lated, nor armed with spines, but longitudinally granulated 
above; terminal joint not quite as long as the preceding, com- 
pressed, and somewhat twisted. Jourth and fifth legs slender, 
short, and subdorsally elevated as in other species of the genus. 
Colour pale yellowish or greyish. The body and legs are 
more or less pubescent. 
From the Mediterranean D. lanata, to which this species 
seems to be most nearly allied, D. armata difters not only in 
the much stronger lateral branchial spines, but in the non- 
tuberculated carapace, the non-spinulose merus joints of the 
second and third legs, &c. In the small West-African ex- 
amples the. chelipedes are feeble, subequal, and the outer 
orbital and lateral branchial spines much smaller. 
Ethusa mascarone (Roux). 
Several specimens (among them males and females) are in 
the collection from Goree Bay, which cannot be regarded as 
specifically distinct from Mediterranean examples, although 
the larger chelipede in the male has the palm deeper and ex- 
ternally somewhat more convex than the male from the Medi- 
terranean in the Museum collection. Colour (in spirits) pale 
yellowish or purplish ; chelipedes (of male) pale, with purplish 
tips. Besides the Mediterranean examples there are speci- 
mens in the British Museum from the Canaries. 
Prof. A. Milne-Edwards has recently described a species, 
Ethusa americana, from West Florida*, which is only dis- 
tinguished from 4. mascarone by the more acute and diver- 
gent rostral spines, more deeply notched orbital margin, and 
more prominent postorbital spine. In these particulars I can 
see no difference between the Mediterranean and African 
specimens of H. mascarone. 
The Hthusa microphthalma is another American species of 
this genus, quite recently described by Prof. 8. I. Smith, 
from the coast of New England}. It is apparently well dis- 
tinguished by the diagnostic characters mentioned by its 
author, ¢. e. the very small eyes and form of the carapace. 
ANOMURA. 
Dromia fulvo-hispida, sp.n. (Pl. XVI. fig. 1.) 
In this species the carapace is a little broader than long, 
moderately convex, and covered with a short close fulvous
