with 5 similar setse. Ovisacs oval pyriform in shape, and projecting on each side 

 beyond the lateral edges of the urosome. 



Colour not yet ascertained. 



Length of adult female 0.96 mm. 



Remarks. This form was described by Poppe in the above-quoted paper 

 as the type of a new Copepod-genus, but its systematic place within the group 

 Harpacticoida was not discussed by that author. Th. Scott, in his List of Crus- 

 tacea of the Clyde area, places it next to Platychelipus littoralis Brady. It is 

 an easily recognisable form, which cannot be confounded with any of the other 

 Harpacticoida. 



Occurrence. The only place where I have met with this peculiar Copepod, 

 is in the immediate neighbourhood of Trondhjem, 2 or 3 female specimens having 

 been taken there, many years ago, from shallow tidal pools on the flat, sandy 

 beach east of the town. Canon A. M. Norman has kindly sent me some specimens 

 taken by him, apparently in the very same place. 



Distribution. Jade Bay, on the North Sea coast of Germany (Poppe), 

 Scottish coast (Scott). 



Gen. 65. NannOpUS, Brady, 1880. 



Syn : Hyophilus, Lilljeborg. 





Generic Characters. Body comparatively stout, with no sharply marked 

 boundary between the anterior and posterior divisions, all the segments sharply 

 marked off from each other. Cephalic segment large, and produced in front to 

 a lamellar rostral projection not defined behind. Urosome tapered behind, with 

 the genital segment in female distinctly subdivided. Caudal rami comparatively 

 narrow, with one of the apical setse very strong, spiniform. Anterior antennae 

 short and thick, 5-articulate and thickly clothed with coarse diverging setse. 

 Posterior antennae strongly built and armed at the tip with strong claw-like spines, 

 outer ramus short, uniarticular, attached near the end of the proximal joint. Oral 

 parts somewhat resembling in structure those in the genus Huntemannia. Natatory 

 legs short and stout, with the outer ramus distinctly triarticulate, inner ramus 

 much shorter than the outer, and in the 3 anterior pairs biarticulate, in the 4th 

 pair very small, uniarticulate ; 1st pair only slightly differing in structure from 

 the 2 succeeding pairs. Last pair of legs, with the distal joint small, in some
