end ; all the segments are more or less angular in shape 

 and with the exception of the cephalic segment, bear each 

 a row of short teeth on the distal margin. Cephalo- 

 thoracic segment broadly triangular in outline, the frontal 

 portion being produced into a small rostrum, and the 

 lateral margins near the distal end into strong curved 

 spines directed backwards and extending slightly beyond 

 the middle of the second segment. Antennules short, 

 five-jointed, all the joints are of moderate length except 

 the fourth which is very short ; the proportional lengths 

 of the joints are as shown in the following formula : — 

 13 . 17 . 22 . 3 . 13 

 12 3 4 5 



Antennae small, two-jointed without any secondary 

 appendage. Mandibles and other mouth organs nearly 

 as in Laophonte. The first pair of swimming feet are 

 similar to those of Laophontodes typicus, and the second, 

 third and fourth pairs are also similar to the corresponding- 

 feet of that species. The fifth pair are large and prominent 

 and project outwards from the sides of the fifth segment ; 

 each foot consists of a single narrow elongate branch, 

 composed of two-joints, furnished with one seta on 

 the inner distal angle of the first joint and two on the 

 outer angle, the second joint has two setae on the inner 

 margin, two on the apex and one on the outer margin, 

 the basal joint has also a row of cilia on its inner margin. 

 Caudal stylets long and narrow, about equal to the 

 combined lengths of the last two abdominal segments. 



Habitat, Off Port Erin, from dredged material collected 

 June, 1895 ; only one specimen has been observed. 



Bernards. — This species is easily distinguished from 

 Laophontodes typicus the only other member of the genus, 

 by the lateral projections of the cephalothoracic segment, 

 the proportional lengths of the joints of the antennules
