peculiarly transformed, being abruptly bent, so as to form a claw-like prehensile 

 appendage. Inner ramus of 4th pair of quite normal structure. Last pair of 

 legs as in the female, 3-articulate; the 1st joint does not, however, answer to 

 the 1st joint in the female, but to the 2nd, as is clearly shown by the bristle 

 issuing from its outer side. Of the other 2 joints, which accordingly answer to 

 the terminal joint in the female, the proximal one is much the larger and carries 

 at the end on each side a seta, whereas the distal joint is quite short with 4 

 diverging setae on the end. 



Body in both sexes of a whitish grey colour, with a slight violaceous 

 tinge. Eye in living specimens very conspicuous and of light red colour. 



Remarks. The present form may be easily recognised from any of our 







indigenous Cyclopoida, both by its characteristic outward appearance and by the 

 rich ornament of coarsely-ciliated setae, which clothes most of the appendages. 

 Especially are these setse very conspicuous on the anterior antennae, where they 

 partly assume a pennate or pectinate character, giving these appendages a peculiar 

 shruppy appearance. It was indeed to this peculiarity that the generic name, 

 Lophopkorus, at first proposed by Brady, alluded. From the 2 Mediterranean 

 species recorded by Dr. Giesbrecht the present form cannot be distinguished 

 without a very close anatomical examination. 



Occurrence. I have met with this pretty form occasionally in 3 different 

 places on the Norwegian coast, viz., in the inner part of the Christiania Fjord, 

 at Ris0r, and at Flekker0, outside Christiansand. The specimens were taken in 

 depths ranging from 20 to 40 fathoms, muddy sand. Canon Norman has taken 

 this form also in the Trondhjem Fjord, at R0dberget, where it occurred in the 

 considerable depth of 150 fathoms. 



Distribution. Coast of England and Scotland (Brady, Scott), Gulf of 

 Naples (Giesbrecht). 



Fam. 3. Cyclopidae. 



Characters. General form of the body resembling that in the typical 

 Cyclopinidce, the anterior division being more or less dilated, the posterior much 

 narrower and attenuated. Head in all the known forms confluent with the 1st 

 pedigerous^segment, and having the rostrum bent in against the ventral face. 

 Anterior antennae more or less elongated and strongly hinged in male. Posterior 

 antennae generally 4-articulate, with an elongated seta at the end of the 1st joint
