Pedipalpi, Ricinulei, and Opiliones. 39 



pair of coxse is proportionately somewhat shorter, being scar- 

 cely half as long again as the distance between its end and the 

 tip of coxa. As both sexes of the new species are to hand, it 

 may be added to the generic description that the sexes differ 

 from one another not only in the two usual points, viz. the shape 

 and position of the genital aperture and the male process on 

 the upper side of fourth tarsus, but besides the abdomen has 

 in the male behind the genital aperture a process directed much 

 backwards, and the median anterior part of the ventral abdo- 

 minal surface is excavated. 



Ogovia nasuta n. sp. 



PI. Ill, figs. 4a — 4c; pi. IV, figs- I a — if. 



Male and Female. 



Body thick, scarcely three-fourths as long again as broad, 

 considerably broader than deep, with the median part of the 

 dorsal surface of abdomen and of the hind part of cephalothorax 

 rather flatly convex. 



Cephalothorax anteriorly produced into a proportionately 

 large, triangular and much vaulted plate (figs, i a and i b) 

 which is somewhat broader than long with the end subacute, 

 the lateral margins a little convex, and the surface densely 

 and finely granulated; this plate overlaps the major part of 

 first joint of the antennulse. The lateral surface between the 

 lamina mentioned and the "conus foetidus" — the process with 

 the aperture of the odoriferous gland at the end — is somewhat 

 hollowed, so that the anterior median part of the cephalothorax 

 is shaped about as a ver\" broad, rounded keel; the posterior 

 transverse furrow is much arcuate, posteriorly at the middle 

 flatly concave and a little or considerabh' nearer to the furrow- 

 limiting the abdomen than the length of the first abdominal 

 tergite at the median line. The surface is ver^'- densely and 

 finely granulated and besides, excepting anteriorly on the sides.
