Carapace very much depressed on the dorsal surface and usually broader than long ; 
narrowest in front, and widening to the postero-lateral margins of the branchial regions ; 
the front is narrow and concave anteriorly ; the interior supraocular angles of the large 
orbits are produced as a lobe or tooth, and there is a stronger spine at the exterior orbital 
angle ; they are somewhat incompletely defined below. There is no epistoma, the buccal 
cavity being narrowed anteriorly and produced between the antennulary fossae to the 
front. The post-abdomen (in the male) is distinctly seven -jointed. Eyes well developed. 
The long and nearly vertically plicated antennules are not capable of being retracted 
within the antennulary fossettes. The basal antennal joint is short and moderately 
robust, and occupies the interior hiatus of the orbit ; the flagellum is well developed. 
The exterior maxillipecles do not cover the anterior part of the buccal cavity ; the ischium 
of the endognath is produced at its antero-internal angle ; the merus is narrow, shorter 
than the ischium, and bears the next joint at its antero-internal angle ; the exognath is 
rather narrow and shorter than the endognath. The chelipedes (in the male) are 
moderately developed and rather large, subequal or unequal, with the merus trigonous ; 
palm moderately compressed (sometimes the palm of one chelipede is considerably 
enlarged); fingers with regular obtuse denticles on the interior margins, and. distally 
acute. The ambulatory legs of the first and second pairs are very considerably elongated, 
with the dactyli slender, elongated, and slightly falcated ; those of the third and fourth 
pairs are very slender, short ; the last pair raised above the preceding, and both 
subprehensile, i.e., terminating in a short, slightly arcuate dactylus, which is inflexible 
against the short penultimate joint. 
The species occur both in the Mediterranean, the West Atlantic, and the Indo-Pacific 
region, in moderately deep water. 
The following are species which have been described since the publication of Milne 
Edwards’s work : — 
Dorippe japonica, v. Siebold. Japan (8 to 50 fathoms); Shanghai. 
Dorippe granulata , de Haan. Japan (to 30 fathoms) ; Hong Kong. 
Dorippe sexdentata, Stimpson. Japan (to 30 fathoms). 
Dorippe armata, White (ined.), Miers. West Africa, Senegambia (to 15 fathoms). 
Dorippe australiensis, Miers. North-East and East Australia. 1 
1 As I have already noted (Crust, in Rep. Zool. Coll. H.M.S. “ Alert,” p. 257, 1884), the common Indo-Pacific species 
designated by Milne Edwards Dorippe quadridentata, is probably the Cancer dorsipes of Linne.
