Indian Deep-sea Dredging. 359 
Length, from tip of rostrum to tip of telson, 92 millim. ; 
of carapace, from supraorbital to posterior margin, 18 millim. ; 
of rostrum, from same point to tip, 26°5 millim. ; of antennal 
seale 13 millim.; of abdomen 50 millim.; of telson 14°5 
millim. 
One female from Station 106, LO9L fathoms, one immature 
in fragments from Station 107, 738 fathoms, and a third 
from Station 117, 1748 fathoms. 
$. A male of about the same size as that of A. Agassizit 
figured by Prof. 8. I. Smith was obtained in a previous 
season 74 miles east of North Cinque Island, in the Anda- 
man Sea, in 490 fathoms. It has a decidedly less elongated 
abdomen than A. Agassizi7; its carapace has much the same 
shape, but the rostrum shows no signs of becoming porrect 
and reduced in length as in that species, for although it is 
broken off just in front of the third tooth of the lower series, 
it still extends fully to the end of the antennal scale. 
Length, from supraorbital margin to tip of telson, 83 
millim.; length of carapace, from supraorbital to posterior 
margin, 23°25 millim.; of antennal scale 15°25 millim.; of 
abdomen to tip of telson 59 millim.; of telson 17°25 millim.

One fine male from Station 116, 405 fathoms. 
Colour in life crimson. 
Length, from tip of rostrum to tip of telson, 144 millim. ; 
of carapace, from supraorbital to posterior margin, 35 millim. ; 
of rostrum, from same point, 34 millim., from front of infe- 
rior spine to tip 17 millim.; of antennal scale 26 millim.; of 
abdomen to tip of telson 75 millim. ; of telson 18 millim. 
It differs from Milne-Edwards’s figure in the following 
peints :—The rostrum is of the same length as the carapace ; 
its basal spines are only four in number; the spine of its 
inferior margin arises midway between its base and its apex, 
and is much more nearly opposite to the middle than to the 
apex of the antennal scale. The branchiostegal spine is con- 
tinued backwards along the side of the carapace as a very 
strong ridge half as long as the antennal scale. ‘The fringes 
of the legs are greatly developed, reminding one of those of 
the last two pairs of legs in Sergestes. ‘The spines of the 
third to the sixth abdominal terga are equal. 
It differs from the specimen figured and described by
