94 MR. T. SCOTT OiS' ENTOMOSTEACA 



ferous, and straiglit terminal spine, iu addition to several smaller spines and a slender 

 plumose seta. The extremity of the outer branches bears a long curved spine, serrate 

 on the outer edge, two smaller dagger-like spines, and a plumose hair ; these smaller 

 spines and the spines at the outer distal angles of the first and second joints are strongly 

 serrate on both margins. A row of spinous setae extends obliquely across the lower 

 middle portion of the last joint of the inner branches of the fourth pair as well as round 

 the extremity of the joint. The fifth pair as in Euterjie gracilis, but with only one short 

 and three long dagger-like terminal spines. A moderately long seta springs from the 

 external margin and near the base of each branch, and a row of small spines extends 

 obliquely from the marginal seta to fully halfway across the segment ; moreover, the 

 extremity and inner margin of each branch are fringed wdth short spinous setee. Ovisac 

 single, large, containing numerous ova. 



Habitat. Station 9, 50 fathoms, January 10th (day collection). Off Accra, svirface, 1 day 

 and 1 night collection ; 3 fathoms, 1 day and 1 night collection, January 16tb. Lagoon, 

 Sao Thome Island, surface, January 27th (night collection). Station 23, 235 fathoms, 

 Eebruary 5th (day collection). Loanda Harbour, surface, February 15th (day collection). 



This species was obtained in 29 tow-nettings, 10 of which were surface and 13 under- 

 surface gatherings ; 4 of the surface gatherings were collected during the day and 12 

 during the night, while 10 of the u nder-surface were collected during the day and 3 

 during the night, as shown by the annexed formula : —

The under-surface gatherings were from depths ranging from 2i to 235 fathoms. 



The form here described, though agreeing generally with Miter;pe gracilis, differs in 

 several important points, as, for instance, in the proportional length of the joints of the 

 anterior antennae, in the inner branches of the third and fourth pairs of swimming-feet 

 being furnished with prominent, strongly setiferous, terminal spines, and in the fifth pair 

 j)ossessing four instead of five terminal spines. These difi'erenccs, which are suflQciently 

 characteristic to allow of the variety being readily distinguished, may ultimately be 

 considered of specific value ; meanwhile, however, I prefer to consider the ' Buccaneer ' 

 specimens as constituting a variety of Eutei^e gracilis.
