401. MR. G. S. BRADY'S MONOGRAPH OF 



11. Cytitere pulchella, nov. sp. 



\rctic type. Distrikution : Recent — Scotland, Baffin's Bay. Fossil — Scotland, glacial clay. 



Carapace of female, viewed laterally, subreniforai, greatest height in front of the 

 middle and equal to considerably more than half the length; anterior extremity broadly 

 rounded, posterior obliquely subtruncate, scarcely rounded ; superior margin highest over 

 the eyes, thence sloping backwards with a gentle curve, inferior sinuated in the middle; 

 outline, as seen from above, ovate, widest behind the middle, greatest width equal to 

 nearly one- half tin 4 length, extremities pointed. Surface of the shell closely punctate. 

 Hinge-teeth of the right valve forming two projecting crests, which end abruptly at the 

 terminal extremities, but slope gradually towards the middle of the hinge-line, and are 

 crenulated on their edges. Upper antennae armed at the apices of the last four joints 

 with slender, slightly curved spines, third and fourth joints coalescent ; flagellum of the 

 lower antenna Particulate, alike in male and female. Mandibular palp bearing three 

 curved pectinate setse (as in Cythereis^S&vs). Feet short and stout, their terminal claws 

 much dilated at the base, nearly straight in the middle, and suddenly curved (almost 



hooked) at the apex. 



Length .V inch.

This species is not very unlike C. villosa in general appearance, but is smaller, less 

 compressed from side to side, with more rounded outlines and a much finer surface- 

 ornament. The only recent British specimen I have seen is one, apparently immature, 

 which occurred in some shell-sand gathered by Mr. D. 0. Drewett in Respond Bay, Loch 

 Erribol, X.B. It occurs more plentifully in some of the Scottish glacial formations, and 

 will be fully figured in a forthcoming work on the Posttertiary Entomostraca. Mr. 

 Orosskey has also found it abundantly in some recent gatherings from Davis's Straits; 

 and horn these specimens the anatomical details above -iven have been derived.

Carapace, as seen from the side, quadrilateral, highest in front, ventricose, often prominently rugose or 



spinous.
