Male of somewhat smaller size than female, and having the genital seg- 

 ment provided helow with a roomy spermatophore-reservoir produced behind on 

 each side to a mucroniform posteriorly-pointing process. Anterior antennae, as 

 usual, geniculate between the 5th and 6th joints. Last pair of legs with the 

 proximal joint simple, not expanded inside. 



Colour light yellowish red. 



Length of adult female 0.28 mm. 



Remarks, I think I am right in identifying the above-described form with 

 Amymone harpactoides of Glaus, as it on the whole agrees rather well with the 

 short description and figures given by that author. It is a very distinct species, 

 easily recognisable by the non-produced genital segment in the female, and the 

 poor development of the posterior maxillipeds and of the last pair of legs. 



Occurrence. Several specimens of this small Copepod were found some 

 years- ago at Skutesnaes, SW coast of Norway, in a depth of about 20 fathoms. 



Distribution. Mediterranean at Messina (Glaus). 



Tegastes calcaratus, G. 0. Sars, n. sp. 



(Suppl. PL -9, fig. 2). 



Specific Characters. Female. Cephalic segment with a well-marked chitinous 

 stripe across the back, postero-lateral corners acutely produced ; rostral prominence 

 distinct, angular. Genital segment forming below 2 thin juxtaposed lamellae, 

 rectangular in front, and each produced behind into a narrow spur-like deflexed 

 process. Distal part of urosome scarcely projecting. Anterior antennae rather 

 slender and distinctly 8-articulate. Posterior maxillipeds of moderate size, with 

 the hand oblong oval in form, palmar edge slightly arched in front, dactylus 

 moderately strong. Last pair of legs with the inner expansion of proximal joint 

 normally developed, anterior edge curved and finely ciliated in its proximal half, 

 carrying moreover the usual 3 short setae, distal joint extending beyond the said 

 expansion. 



Colour not yet ascertained. 



Length of adult female 0.30 mm. 



Remarks. This new species is easily distinguishable from the other known 

 species by the peculiar spur-like processes issuing from the genital segment below, 





a character, which has given rise to the specific name here proposed. 



Occurrence. Only a single female specimen of this form has hitherto come 

 under my notice. It was found in a sample taken at Bukken, SW coast of Nor- 

 way, from a depth of about 20 fathoms.
