bear on the dorsal surface of the second and third segments of the abdomen 

 a cluster of enormous spermatophores, the adhesive material of which almost 

 covers and obscures the segments themselves. 



Diaptomus, sp, 



A collection from Resht contains three species of Diaptomus, but unfortu- 

 nately every specimen is badly damaged and I am unable to name any of 

 them. Of one species there are two male specimens of enormous size which 

 resemble Hemidiaptomus ignatovi, Sars, but both of them lack the prehensile 

 antenna and the fifth pair of legs. 



4, Ostracoda. 



Notodromas persica, n. sp. 



A few specimens of a small species of Notodromas were found in a collection 

 from Resht (N. W. Persia) but the shells are so soft and distorted that a 

 satisfactory description of their shape cannot be given. Neither valve shows 

 any sign of spines. The outline figure given is taken from a mature female 

 which was comparatively undistorted, but, having regard to the softness of 

 the shell, too much reliance must not be placed upon it. The two sexes seem 

 to be alike in shape.

 of adult male. 4. First leg of adult male. 6. First leg of young male. 6. Pre- 

 hensile appendage of left side of male. 7. Prehensile appendage of right 

 side of male. 



The second antennae consist of five joints only, the third and fourth being 

 fused. The arrangement of setae is as in N. monacha. The large seta borne on 

 the anterior lower corner of the second joint is as long as the next two joints 

 combined, extending to the apex of the limb. 



The first maxilla of the male bears very large prehensile orangs. That of 

 the right side consists of an elongated stem, somewhat swollen at its base, and 

 a large sickle- shaped hook, denticulate at its extremity and bearing a broad
