Bernards. This is one of the smallest known Cumacea, and may thus 

 easily escape attention in an examination of the contents of the dredge. It is, 

 however, an easily recognizable form, being clearly distinguished in both sexes 

 from our other Cumacea. As is generally the case in this order, the sexual 

 dimorphism is very pronounced, and indeed the adult male looks so different from 

 the female, that it was at first regarded by the Rev. Mr. Norman as belonging 

 to a distinct species, C agilis. 



Occurrence. Though nowhere in any abundance, this form seems to occur 

 along the whole south and west coast of Norway, from the Christiania Fjord to 

 the Lofoten Islands. It is generally found in comparatively shallow water, on a 

 sandy bottom covered with a thin layer of blackish mud, sometimes also at the 

 roots of Laminarise. The adult males are very agile, and have been taken by 

 English naturalists (Robertson) rather abundantly in the tow-net at night. 



Distribution. British Isles (Norman), Heligoland (Ehrenbaum), Mediter- 

 ranean at Messina and Spezia (the present author). 



Farn. 8. Campylaspidae. 



Characters Body comparatively short and robust, with the anterior 

 division much dilated and boldly arched above. Carapace of unusual size, more 

 or less depressed in front and strongly vaulted behind. Five pedigerous segments 

 exposed behind the carapace, the 2 anterior ones, however, very short, band-like. 

 Caudal segments more or less depressed, the last one short, pentagonal. Integu- 

 ments greatly indurated. Eye present, though rather imperfectly developed. 

 Superior antenna? of exactly the same structure in the two sexes; inner flagellum 

 rudimentary. Inferior antennae in female imperfectly developed and without any 

 setse, in male attaining the length of the body. Oral parts of a structure rather 

 different from that in other Cumacea, some of them being very fully developed, 

 others rather imperfect. The 2 anterior pairs of legs in female, and all but the 

 last pair in male provided with exopodites. Pleopoda wanting in male. Uropoda 

 with the rami comparatively short, the inner uniarticulate, the outer biarticulate. 

 No telson.
