Genus Saphirinella, Glaus. 

 Saphirinella, Claus, Die freilebendea Oopepodeu, 1863. 



Saphirinella stylifera (Lubbock). 



1856. Saphirina sttjlifera, Lubbock, Trans. Ent. Soc. vol. iv. p. 28, pi. iv. figs. 9, 10.

Habitat. Station 2, 5, 25, and 50 fatboms, January 1st (uigbt collections). Station 3, 

 25, 50, and 100 fatboms day tow-nettings, and 50 fatboms nigbt tow-netting, January 2nd. 

 Lat. 1° 55' 5" N., long. 5' 55' 5" E., 10, 20, 30, 60, 260, aud 3C0 fatboms, January 22nd 

 (day collections). Station 23, surface, 20, 85, 185, and 235 fatboms, February 5tb 

 (day collections). 



Saphirinella stylifera was obtained in 58 tow-nettings, 37 of wbicb were day and 21 

 Avere nigbt collections. 47 of tbe collections were under-surface, tbe otbers were surface 

 gatberings, as sbown by tbe annexed formula : — 



j 1 dav collections, 

 r 11 surface | 7 nigbt ditto. 



Tow-nettings 58 <^ oq i y,, 



1-17 under-surface ( 33 day ditto. 

 1 11 nigbt ditto. 



Tbe under-surface tow-nettings included gatherings from 5 to 360 fatboms, in nearly 

 all of wbicb Saphirinella was more or less frequent. 



Many specimens of Saphirinella were obtained, but tbey all appeared to belong to the 

 one species Saphirinella stylifera (Lubbock). Very few specimens were observed in tbe 

 ' Challenger ' collections, which is the more remarkable considering the number of 

 gatberings and the extensive area represented. 



Note. — Saphirinella : It has been sbown by Dr. Giesbrecbt that Saphirinella is only 

 tbe male form of Copilia, and that Saphirinella stylifera, Lubbock, is the male of Copilia 

 mirabllis, Dana. 



Saphirella, nov. gen. (Provisional name.) 



Anterior antenna? nearly as in Saphirina, 5-jointed. Posterior antennae 3-jointcd. 

 Mandibles stout, each bearing a strong terminal conical tooth, serrate on both margins, 

 and a stout plumose terminal spine. Maxilla? broadly subquadrangular and furnished 

 with a few terminal seta?. Posterior foot-jaws stout, 3-jointed, and armed with a mode- 

 rately strong terminal claw. The swimming-feet arc 2-branched, each branch consists of 

 a single broadly foliaceous joint ; fifth pair rudimentary or obsolete. 



Saphirella abyssicola, n. sp. (PI. XIII. figs. 57, 58; PL XIV. figs. 5-10.) 



Length 1'2 mm. Cephalothorax robust ; the first segment, which is about as long as 

 broad, is fully two-fifths tbe length of the whole animal ; the triangular postero-distal 

 angles of tbe second segment are extended backwards to near tbe end of tbe fourth
