214 ON COPEPODA AND OTHER CRUSTACEA 



Genus DELAY ALIA, Brady. 



Delavalia pygmaea, n. sp. (Plate IIL, figs. 5-10). 



Fanale. — Antennules (fig. 5) eight-jointed, short and rather 

 stout, scarcely as long as the first cephalo-thoracic segment, 

 clothed with numerous long hairs, first and third joints con- 

 siderably longer than the rest, which, except the very short 

 fifth, are nearly equal in length. Antennae (fig. 6) quite equal 

 in length to the antennules, bearing a long, slender three-jointed 

 secondary branch, the middle joint very short. Inner branch 

 of the first pair of feet (fig. 7) equal in length to the outer 

 branch, two-jointed and destitute of setae except at the apex, 

 the distal joint equal in length to the two terminal joints of 

 the outer branch ; outer branch composed of three equal 

 joints, first and second joints bearing a single stout seta at 

 the external distal angle, last joint with four slender apical 

 setae : second, third, and fourth pairs sparingly setiferous 

 (fig. 8), the outer branch longer than the inner. Fifth pair 

 (fig. 9) small and foliaceous, basal joint very wide and short, 

 bearing five rather widely separated setae on the inner lobe, 

 and one seta on the outer angle; second joint obovate, its 

 distal margin bearing four subequal setae. Caudal stylets 

 (fig. 10) short, fully twice as long as broad, the longest of the 

 terminal setae about thrice as long as the stylet. Male un- 

 known. 



One specimen only was taken, and this was dissected with- 

 out measurements and general drawings having been made. 

 The mouth organs were not seen, but the general aspect of 

 the animal agreed with that of the family to which it belongs. 

 It is, however, much more minute than other described species 

 of Delavalia. 



Genus AMEIRA, Boeck. 



Ameira breviremis, n. sp. (Plate III., figs. 11-14; 



Plate IV., figs. 1-6). 



Female. — Animal rather robust and stout, rostrum short and 

 slender, limbs unusually short (Plate 4, fig. i), caudal stylets
