of the prawn to which it has been affixed; hence, in our 
right-hand figure, representing the dorsal view of the 
female, the head is seen to the left of a straight line, the 
lateral margins of the body to the right being distended, 
whilst those of the opposite side are contracted in a 
corresponding degree; the head itself does not project 
beyond the general outline of the body, which is almost 
continuous, and its anterior edge is rather sharp; the 
hind part is considerably contracted, and very deeply 
immersed in the anterior segment of the body; the eyes 
are wanting in this sex. The antennz are very small, 
the outer pair being composed of three short, broad 
joints, gradually diminishing in size, the last terminating 
in a minute point, which may possibly represent the 
flagellum ; the inner pair appear to be only formed of 
two distinct joints, of which the basal one is nearly 
circular. 
The rudimental mouth is covered by a large pair of 
foot-jaws (maxille), flattened, with the inner margin 
(where the two meet together) nearly straight, the inner 
apical angle being provided with a small, nearly circular, 
lobe or joint, clothed with small hairs, and the base of 
this pair of foot-jaws is furnished with two or three 
membranous, flattened, pointed appendages. The an- 
terior pair of the scales forming the incubatory pouch 
are transverse, and furnished with a large, flattened, 
curved lobe, of which the extremity is obtuse and in- 
curved. The other scales are affixed within the base of 
the legs, the hinder extremity of each overlapping the 
succeeding scale. 
The seven pairs of legs are of equal size and similar 
in form, being short and thick, having a broad, oval 
hand, terminated by a small finger. They are generally 
folded back and concealed beneath the lateral margins of
