Parthenope ( Parthenomerus ) efflorescens, n. sp. 
Carapace triangular, not quite f as long as broad; its entire sur¬ 
face, above and below, as also that of the sternum, of the abdomen (in 
the female), and of all the exposed appendages—from the eye-stalks 
to the last pair of ambulatory legs, covered with a lace-work, or frosting, 
formed by the partial contact of very delicate crisply paxilliform gra¬ 
nules. There are no large tubercles, and, except on the arm hand and 
fingers, no spines. On the arm, namely, there are two or three teeth 
with acicular tips, on both the lower-inner, and the upper-inner borders ; 
on the hand there are three needle-like teeth on the upper-inner, and 
three on the lower-inner borders; and the fingers are everywhere beset 
vrith long needle-like spines. The rostrum is nearly vertically deflexed. 
Only one clieliped remains in our unique specimen ; and it, which 
is a little over twice the length of the carapace, has a most curious 
tapering form: the meropodite is huge and thigh-shaped, decreasing 
in size distally; the carpus is slenderer than the end of the meropodite; 
and the hand is still slenderer than the carpus : the fingers are long — 
nearly as long as the palm — are extremely slender, and, as already 
noted, are beset with long slender spines. 
A single female, from the Andaman Sea, 36 fathoms.

Carapace very broadly triangular, with very large lateral clvpei- 
form vaulted expansions which completely conceal the ambulatory legs, 
and are prolonged posteriorly far beyond the base of the abdomen; a 
large space between the gastric and the cardiac regions is triangular 
and concave. The rostrum is nearly horizontal, spatuliform and very 
prominent. The pterygostomian regions are smooth, not ridged. The 
orbits are very small, nearly circular, with a suture in the superior 
margin. The epistome is well developed; the antennulary fossae are 
narrow and somewhat oblique. The abdomen, in the male, is five- 
jointed ; the third to fifth segments coalescent. The eyes are very 
small and retractile. The basal antennal joint is slightly dilated and 
does not nearly reach the internal orbital hiatus, which is filled by the 
second joint. The buccal cavity and external maxillipeds are small. 
The ischium-joint of the maxillipeds is not produced at its antero-internal 
angle; the merus is distally truncated, with the antero-external angle 
slightly produced, the interior margin notched below the antero-internal 
angle. The chelipeds are nearly as in Lambrus; the merus-joint has a 
wing-like lobe on the posterior margin near to the distal extremity; the
