from it to the gastric region; the carapace is crossed in its 
widest part by a transverse series of six granulated elevations 
or tubercles, of which the two median are situated on the 
gastric region ; posterior to these is another granulated pro- 
minence. The cardiac region is obtusely rounded and very 
convex; there are usually two slight prominences on the 
antero-lateral margins of the carapace, one on the postero- 
lateral margins, and two rounded lobes, which are sometimes 
confluent, on the posterior margin. The fissures of the upper 
orbital margin are indistinct or sometimes quite obliterated. 
The male postabdomen has its third to sixth joints coalescent. 
The antennulary fosse communicate with the orbits by the 
cavity at the inner suborbital angle, which is also partly oc- 
cupied by the basal antennal joints. The outer maxillipedes, 
legs, and the inferior surface of the carapace are granulated ; 
the exognath of the maxillipedes is robust, with a nearly 
straight outer margin, and does not reach to the extremity of 
the triangulate merus joint of the endognath. ‘The chelipedes 
(in the adult male) are closely granulated, the granules often 
acute; the arm or merus is slender and, like the carpus, 
destitute of prominent spines or tubercles; the palm has two 
slight prominences on its upper margin, and is rather convex 
on its inner surface; fingers compressed, acute at apex. Am- 
bulatory legs short, slender, the joints (except the last) some- 
what compressed, margins with acute granulations; terminal 
joints slender, pubescent. Colour (in spirit) yellowish or 
grey, often tinged with pimk, sometimes with irregularly- 
disposed punctulations of a more intense purplish pink. Length 
of largest male a little over 5 lines (11 millim.), breadth 
about 6 lines (nearly 13 millim.) ; length of chelipede a little 
over 7 lines (15 millim.). 
A good series of both sexes is in the Museum collection. 
The tuberculations of the carapace are more distinct in some 
specimens (from which the description is taken) than in others, 
where they are rather to be described as rounded prominences. 
In the females they are sometimes nearly obsolete. ‘he 
margins of the postabdomen are usually marked with red 
spots. I very much doubt the generic distinctness of Phlyata 
from Hbalia: the presence or absence of supraocular fissures is 
not a character of much importance; and the antennulary 
fossettes certainly communicate with the orbits in some species 
of Hbalia (e.g. in adult H. tuberosa). 
There is a specimen from the Canaries, and another from 
Madeira, in the collection of the British Museum which have 
the carapace everywhere evenly and distinctly granulated, and 
scarcely any trace of the transverse series of prominences,
