102 ME. T. SCOTT ON ENTOMOSTEACA 



Genus Harpacticus, Milne-Edwards (1838). 

 Harpacticus chelifer, ?var. (PI. XII. figs. 42-46.) 



1776. Cyclops chelifer, Miiller, Zool. Dan. Prodr. 2413 ; Entomostraca, p. Hi, t. xix. figs. 1-3. 



1850. Arpacticus, Baird, Brit. Entom. p. 212, t. xxix. figs. 2, 3, 3 a-g. 



1863. Harpacticus, Clans, Die freilebendeu Copcpoden, p. 135, t. xix. figs. 12-19.

A form of Harjiacticus closely resembling Harpacticus chelifer was obtained in a 

 shore gathering collected at Accra, January 16th, and in a tow-net gathering from 

 185 fathoms at Station 23, collected February 5th. 



The chief point of difference seems to be the absence of the curved spines or " claws " 

 on the inner distal margin of the last joint of the posterior foot-jaws ; the inner margin 

 of these foot-jaws is also not concave as in S. chelifer, but in all other respects the 

 ' Buccaneer ' specimens closely resemble that species. 



Genus Miracia, Dana. 



Miracia, Dana, Proceed. Amer. Acad. Sci. 1849. 



Miracia efferata, Dana. 



Habitat. Station 2, 50 fathoms, January 1st (night collection). Station 9, surface, 

 25 and 50 fathoms, Jahuary 10th (day collections). Station 14, 10 fatlioms, January 

 21st (night collection). Lat. 1° 55' 5" N., long. 5° 55' 5" E., 10 to 360 fathoms, 

 January 22ud (day collections). Lat. G" 3' 3" S., long. 11° 7' 5" E., surface, Eebruary 8th 

 (day collection). 



This Miracia was observed in 49 tow-nettings, 18 of which were surface and 31 under- 

 surface gatherings. The uuder-surface gatherings were from 3 to 360 fathoms, 8 of the 

 surface and 21 of the under-surface tow-nettings were day collections, while 10 surface 

 and 10 under-surface were night collections, as shown by the formula : — 



f 8 day collections.

 It was of frequent occurrence in several of the gatherings, and many of the specimens 

 carried ovisacs. 



MlKACIA MINOR, u. sp. (PL XI. figs. 18-30.) 



Length -93 mm. General form as of Miracia efferata, but not half the size. Anterior 

 antennce 8-jointed, slender in the female ; the proportional lengths of the joints are as 

 follows : —
