Harpacticoida 

 Fam. Longipediidae. 



Gen. Sunaristes, Hesse. 

 10. Sunaristes paguri. Hesse. 



(PI. XII). 

 See Vol. V, p. 15, PI. VI & VII. 



Specific Characters. Male. Body still more slender than in female, 

 with no sharp demarcation between the two chief divisions, the posterior seg- 

 ments of the trunk being scarcely wider than those of the urosome and of 

 simple cylindrical form, without any distinct epimeral plate's. Urosome com- 

 posed of 5 well defined segments, the 1st of which (the genital segment) is 

 only slightly larger than the succeeding one, and somewhat protuberant at the 

 end below; last segment, as in the female, much smaller than the others. 

 Caudal rami of same appearance as in the female. Anterior antennae very 

 strongly built, and pronouncedly subcheliform, each terminating in a power- 

 fully developed hand, with a well-marked projecting angle in front defining 

 the palmar edge, against which the clawshaped terminal joint, or daetylus, 

 admits of being impinged. Posterior antennae and oral parts exactly as in the 

 female. Natatory legs likewise very similar, with the exeption of the 2nd pair, 

 the inner ramus of which is conspicuously transformed, its 1st joint being produced 

 at the end outside to a very strong mucroniform process extending beyond 

 the middle of the terminal joint. Last pair of legs still more rudimentary than 

 in female, all the setae arising immediately from the corresponding segment, 

 without any intervening lamella. Genital lobes closely approximate and of 

 obtusely triangular form, each carrying outside near the end a slender seta. 



Length of the specimen examined 2.15 mm. 



Remarks. Of this peculiar Copepod only the female sex was described 

 in Vol. V. I now add the above short diagnosis of the male, and on PI. XII
