varieties above enumerated of L. massena, the carapace is 
more depressed than in that species, and the front elongated 
triangulate acute or subacute, and scarcely at all deflexed. 
There are a few small granules on the summit of the gastric, 
cardiac, and branchial regions, and in the interspaces between 
the two last mentioned, and on the posterior margin; but the 
anterior part of the carapace, rostrum, and the sides of the 
branchial regions are smooth; the branchial regions are ob- 
liquely carinated, the carina reaching to and most distinctly 
defined near the postero-lateral margins. The chelipedes 
have the arms distinctly tuberculated ; palms smooth on the 
upper surface. Colour (in spirit) yellowish brown or pinkish. 
Length and breadth of the largest example about 6 tines 
(124 millim.). 
Four specimens (males and females) are in the collection 
from Goree. There is also in the British Museum a male 
from the Canaries. 
This well-marked form may be distinguished from P. eapan- 
sus, Miers, by not having the carapace nearly so much produced 
over the bases of the ambulatory legs, the acute rostrum, and 
other points. 
It bears some resemblance to the variety figured by Costa * 
of the form he designates Parthenope contracta ; the carapace, 
however, is broader, not indented on the sides of the hepatic 
regions, and there is no prominent spine on the cardiac region. 
The typical P. contracta is regarded by Heller and others as 
synonymous with P. massena. 
Heterocrypta Malizami, sp. n. 
(Ge; SOUUL, aie, 1) 
In this species, of which I have seen a large number ot 
specimens of both sexes from Goree, the carapace is penta- 
gonal rather than triangulate, the lateral margins at first 
widely divergent, and afterwards nearly parallel ; the gastric, 
cardiac, and branchial regions convex ; the gastric region is 
posteriorly steeply inclined ; anteriorly it slopes gently down- 
ward to the front, which is very prominent, nearly horizontal, 
smooth, and flat above, with the sides slightly arcuated and 
the apex subacute; the sides of the anterior face of the gastric 
prominence are sharply defined and usually somewhat granu- 
lated ; the cardiac prominence has the form of a large, very 
distinctly defined granulated tubercle; on the branchial 
regions is a sharply defined oblique granulated ridge that 
extends from the postero-lateral angles of the carapace nearly
