Remarks. The above-described form seems to be that originally recorded 

 by Philippi as the type of his genus Laophonte. It has erroneously been identi- 

 fied by Brady and other British authors with Cleta serrata of Glaus, which is a 

 different species, to be described below. On the other hand, is the form described 

 by Glaus from a male specimen as Cleta forcipata undoubtedly identical with the 

 present species. I am also of opinion that the form recorded by Seb. Fischer 

 as Harpacticus fortificationis is referable to the same species. It is one of the 

 largest species, and is moreover easily recognizable both by its general appearance 

 and by the structure of the anterior antennae and that of the 1st and last pairs 

 of legs. 



Occurrence. This pretty species is not unfrequently found along the whole 

 south and west coast of Norway, at least up to the Trondhjem Fjord in moderate 

 depths among algae, and is at once distinguished from most other species by its 

 comparatively large size and the very dark colour of the body. 



Distribution. Mediterranean (Philippi), Madeira (Fischer), British Isles 

 (Brady).

Specific Character*. Female. General form of body rather like that in 

 the preceding species, though perhaps somewhat less slender. All segments very 

 sharply marked off from each other by deep constrictions, whereby the dorsal 

 line acquires a pronouncedly jagged or serrate appearance; posterior edge of the 

 segments fringed with densely crowded short spinules acute at the tip. Cephalic 

 segment comparatively larger than in the type species, rostral projection rather 

 prominent and terminating in 2 juxtaposed knob-like points. Urosome shorter 

 than the anterior division of the body, all its segments, except the last, lamellarly 

 expanded laterally, last segment about the length of the preceding one, anal 

 opercle fringed with uniform spinules. Caudal rami scarcely as long as the anal 

 segment and not tapering distally, being, in addition to the setse, clothed both 

 outside and inside with scattered spinules, tip transversely truncated and carrying 

 2 well-developed setae jointed near the base, the inner one much the longer, setse 

 of the outer edge approximate and attached considerably behind the middle. An- 

 terior antennae scarcely exceeding half the length of the cephalic segment, but 



31 Crustacea.
