palm slightly compressed, not dilated, armed with spinules on its upper 
and lower margins, fingers about as long as palm, and slightly incurved 
at the apices which are nearly destitute of hair; the ambulatory legs 
are very slender and elongated; the dactyli of the first three pairs are 
short and nearly straight, in the last pair only are they slightly falciform. 
Colour (in spirit) light yellowish-brown.” (Miers). 
A single specimen is included in the Museum collection: the locali¬ 
ty is not quite certain, but it came most probably from the Andamans. 
Achseus cadelli , n. sp. Plate Y. fig. 1. 
In general form and proportions much resembling Achseus lorina 
(Ad. & White), from which it differs in having the legs even more 
slender, and the eye-stalks quite smooth. 
The regions of the pyriform carapace are well demarcated, the 
hepatic regions being each produced to form a strong sharp tooth. 
There are three elevations, arranged in triangle, on the gastric region, 
and tw T o, side by side, on the cardiac region. 
The rostrum has the usual Achseus- form, but each lobe is dorsally 
carinate, the carina being spinate or serrate. 
Behind the rostrum is a long constricted “ neck,” more pronounced 
even than that of A. tenuicollis and brevirostris. 
The chelipeds are of the usual form. The legs are extremely long 
and slender, those of the second trunk segment being about five times 
the length of the carapace, rostrum included. The dactyli of the 4th 
and 5th pairs are hardly falciform. Length of carapace, 7 millim : 
greatest breadth of carapace, 4 millim. : length of 2nd pair of trunk-legs, 
36*5 millim.

Achseus spinosus, Miers, Japanese and Corean Crustacea, in Proc. Zo ol. Soc., 
1879, p. 25. 
Carapace triangular, narrowed behind the eyes, and armed with 
six spines above, namely : one on the gastric, one — bilobed—on the 
cardiac, and two on each branchial region : there are also some spines 
or sharp tubercles on the ventrad aspect of the hepatic and branchial 
regions. The rostrum is small and bilobed. The eye-stalks are robust, 
and have a strong tubercle near the middle of the anterior surface. 
Chelipeds in the male robust, the arm and wrist granular above, the 
palm swollen, with about six spinules on the upper margin and a few 
granules on the lower margin near its base : fingers, in the male, acute
