though small, is well formed and could hardly be described as a 
mere papilla. 
Hitherto this species was only known from a single specimen ; 
but a third example is preserved in the Museum collection. 
This specimen measures 76 mm. in length and was obtained at St. 
297. 13-iv-02. Gulfof Oman; 25°11’ 30” N., 57° 15’ E. 689—700 
fathoms. 
Family HOPLOPHORIDAE. 
Hoplophorus gracilirostris, A. Milne-Edwards. 
Hoplophorus gractlirostris, Alcock, 1901, p. 73. 
A single male, about 55 mm. in length, was taken at St. 391. 
Family PANDALIDAE. 
Pandalus (Plesionika) martius, A. Milne-Edwards. 
Pandalus (Plestontka) martius, Alcock, 1901, p. 95. 
Three damaged specimens, one an ovigerous female, appear 
to belong to this species. They were obtained at St. 391. 
Heterocarpus gibbosus, Bate. 
Heterocarpus gibbosus, Alcock, 1901, p. 103. 
Three small specimens were found at St. 391. In all these 
examples the rostrum is considerably longer than in adults and 
exceeds the median length of the carapace.

Merhippolyte calmani, sp. nov. 
(Pl. i, figs. r—4.) 
The general form is slender and the surface of both carapace 
and abdomen is glabrous and without trace of punctation. The 
rostrum is twice, or rather more than twice, the length of the 
carapace, straight to the end of the second joint of the antennu- 
lar peduncle and thence to the apex very strongly ascendant. 
The vertical height of the apex above the dorsal line of the 
carapace continued forwards is about equal to the carapace-length. 
At its base the rostrum is armed with three large and almost 
equidistant teeth; the median one is situated directly over the 
orbit, while the anterior one reaches about to the end of the 
eyes. At the extreme apex there is a small dorsal tooth but the 
upper margin between this point and the eyes is wholly unarmed. 
On the ventral edge there are ten teeth, large and closely set 
towards the base, smaller and more distant towards the apex. 
Between the proximal teeth of both margins there are a few setae. 
All the teeth are fixed. The rostral carina is continued backwards
