Hungry Bay, Bermudas. A male and female were obtained in the Mangrove Swamps. 
In these specimens the notch in the middle of the frontal margin is obsolete ; in 
other particulars they agree with the excellent description and figure of M. A. Milne- 
Edwards of this species. 
The dimensions of these specimens are as follows ; —

Pseuclozius, Dana. 
Pseuclozius, Dana (pt.), Amer. Journ. Sci. and Arts, ser. 2, vol. xii. p. 127, 1851 ; U.S. Explor. 
Exped., vol. xiii., Crust. 1, p. 229, 1852. 
Carapace markedly transverse, depressed, with the dorsal surface nearly smooth, not 
lobulated, and with the teeth of the antero-lateral margins sometimes developed, some- 
times obsolete ; the sutures of the dorsal surface (except sometimes the postfrontal or 
mesogastric suture), are not distinguishable. The front is moderately deflexed, usually 
less than one-third the width of the carapace, and its anterior margin is sinuated or 
obscurely bilobate or quadrilobate ; the orbits are small, with the margins entire. The 
ridges of the endostome or palate are wdiolly or partly developed. The post-abdomen in 
the male is distinctly seven-jointed (in the species I have examined). The eye- 
peduncles are set on very short pedicels. The antennules are transversely plicated. 
The basal peduncular joint of the antennse is short, and does not attain the infero- 
lateral angles of the front. The ischium of the outer maxillipedes is not produced at its 
antero-internal angle ; the merus is distally truncated, with the antero-internal angle 
scarcely, or not at all, emarginate, and the antero-external angle usually not prominent. 
The chelipedes in the adult male are moderately robust ; carpus bluntly toothed on its 
inner margin, palm nearly smooth, rounded above, fingers toothed on the inner margins 
and distally acute. The ambulatory legs are of moderate length, with the joints 
smooth, slightly compressed, but not carinated. 
This genus is very nearly allied to Menippe, de Haan, 1 from which it is scarcely 
1 Corresponds nearly to Pseuclocar cinus, A. Milne Edwards ; I propose to restrict this latter designation to the 
Pseudocarcinus gigas (Lamarck).
