206 Mr. E. J. Miers on Crustacea from 
DECAPODA. 
BRACHYURA. 
Stenorhynchus rostratus (Linn.). 
Several small specimens, both males and females, are in 
the collection ; the length of the cephalothorax of the largest 
to tip of rostrum is only about 7 lines (15 millim.). 
In all of these specimens the rostrum is very short, the 
epistome and basal antennal joint are without spines, and the 
anterior legs nearly smooth; the long vertical spines on the 
gastric and cardiac regions of the carapace are in most of 
these specimens more developed than in the numerous Huro- 
pean specimens of S. rostratus in the collection of the British 
Museum. 
An adult male in the collection—length of carapace about 
84 lines (18 millim.)—differs from the foregoing and from 
typical specimens of S. rostratus in having the anterior legs 
or chelipedes armed with numerous spinules on the upper and 
lower edges of the arms, wrists, and hands, which joints are 
ordinarily in S. rostratus smooth or simply granulated; the 
fingers, which are dilated and laterally compressed, are smooth, 
and when closed have between them, near the base, a wide 
hiatus. A specimen collected by W. 8S. Kent, Hsq., during 
the ‘ Norma’ Expedition, in Vigo Bay (which, however, has 
the rostrum broken), and one from Belfast Bay, dredged 
in 20 fathoms (W. Thompson, Hsq.), present similar cha- 
racters. 
This variety differs from 8. egyptius, S. Czernjawskit, and 
S. longirostris in the very short rostrum and by the absence 
of the minute spines at the base of and upon the basal antennal 
joimt, and may be designated var. sprnulosus. 
Herbstia violacea. 
Micropisa violacea, A. M.-Edwards, Nouv. Archiv. Mus. Hist. Nat. iy. 
p- 50, pl. xvi. figs. 8-6 (1868). 
To this species I refer a series of small specimens (both males 
and females). Length of the largest about 9 lines (19 millim.), 
breadth about 7 lines (nearly 15 millim.). 
The spines of the carapace show great variation in the 
degree of their development. In all the specimens I have 
examined the chelipedes have the inner margins of the fingers 
smooth, not denticulated. Specimens are in the British 
Museum (preserved dry) from the West-African coast,
