In the female the width of the posterior segments decreases gradually 
instead of abruptly. 
The antennules of the male are modified to form powerful grasping 
organs, as shown in the drawing (fig. 2). 
The distribution of this curious species appears to be local rather than 
rare, and since its discovery in the crevices of decaying fragments of 
wood, its occurrence in similar situations has occasionally been noticed 
both in the Firth of Forth and the Firth of Clyde, and it may probably 
be found in such situations round other parts of our shores.

It is thirteen years since a description of this species was first 
published in the Board’s Twelfth Annual Report. The description was 
prepared from female specimens, the male being at that time unknown ; 
and as,so far as I know, it has not yet been recorded, the following 
observations on its structure, with some additional remarks on the female, ~ 
will render the former description more complete. 
This species, like the last, is very small, the largest of our female 
specimens is scarcely °5 millimetre (about 5 ‘of an inch) in length, while 
the males are only about one-sixtieth of an inch; they may therefore be 
easily overlooked. 
In both the male and female the body is elongated and narrow, and is 
considerably depressed (fig. 6). The male, though smaller than the 
female, does not differ much from it in general appearance. 
The anterior antenne in the male are composed of the same number oi 
articulations as those of the female, but the last three joints are 
considerably modified, as shown in the drawing (fig. 7). The third joint 
is small, the uext is dilated and gibbous, while the last forms a slender 
hook-like process. 
The mandibles are very small, and the biting-edge is armed with a 
few prominent teeth. The mandible-palp consists of a single small one- 
jointed branch bearing several setz (fig. 8). 
The maxille are similar to the same organs in typical species of 
Laophonte, and consist of a broad masticatory lobe provided with 
several elongated slender spines, and a small bilobed palp (fig. 9). 
The first maxillipeds are small but moderately stout, and the basal 
joint, which is somewhat dilated, is provided with a small setiferous 
process on the inner margin, while the end joint terminates in an 
elongated and moderately strong claw (fig. 10). The second maxillipeds 
are as previously described. 
The first pair of thoracic feet are in structure nearly as in Laophonte, 
the inner branch being short and three-jointed, while the outer, which is 
two-jointed, is stout and furnished with a strong teaminal claw (fig. 11). 
The second pair, like the first, is somewhat similar in the two sexes; 
the outer branch is slender and elongated and composed of three sub- 
equal joints, while the inner is short and two-jointed ; the first joint of 
the inner branch is extremely small, but the second, though very slender, 
is of moderate length and furnished with tyo slender apical setze. The 
third pair in the female is similar in structure and armature to the 
second, but the inner branch of this pair in the male has two peculiar
