54 ME. T. SCOTT ON ENTOMOSTEACA 



forms a produced lobe-like process ; the last joint small, curved imvard, and bearing a 

 minute bent terminal spine. The (?) right foot is longer than the other and 5-jointed ; 

 the first joint is about twice the length of the first joint of the (?) left foot, but the first 

 and second joints of the (?) right are together scarcely equal to the length of the same 

 joints of the other foot ; an elongate appendage — ? as long as the third joint — springs from 

 the end of the second joint ; the third and fourth joints, which are subequal in length, are 

 more slender than the preceding joint, and are together nearly equal in length to the 

 first ; the fifth, which is scarcely so long as the fourth and appears to be connected with 

 it by a hinged articulation, is ciliate on the inner edge. 



Habitat. Lat. 4° 26' 7" S., long. 10° 1' 8" E., in a tow-net gathering from 235 fathoms 

 collected between 11 a.m. and 3.30 p.m. February 6th. 



This Scolecithrix somewhat resembles Amallophora in the form of the feet of the fifth 

 pair, but differs in the number and proportional length of the joints. It also differs from 

 any other Scolecithrix described in tliis Report in the proportional length of the joints of 

 the anterior antenna;, the form of the anterior foot-jaws, and the fifth pair of feet. 



Subgenus Amallophora *. 



(Subgenus of Scolecithrix, Brady.) 

 Anterior antennsB 20- to 23-joiuted. Mouth-organs and swimming-feet nearly as in 

 Scolecithrix, except that the anterior foot-jaws are furnished with one or more appendages, 

 each consisting of a bundle of filaments resembling a sheaf of corn in miniature. 

 Fifth pair of feet in the male dissimilar, 1- or 2-branched, prehensile ; in the female 

 siuiple, 1-branclied. 



Amallophora tvpica, n. sp. (PL III. figs. 39-lG ; PI. VI. figs. 1-1.) 



Length 2"7 mm. (about l-9th of an iuch). .Body elongate, moderately stout ; forehead 



rounded. Anterior antennai rather longer than the body, 20-jointed, and sparingly 



setiferous. The formula shows approximately the proportional lengths of the joints : —

The first seven joints bear short club-shaped appendages. Primary branch of the 

 posterior antenna? short, secondaiy branch moderately long, the intermediate three very 

 short (fig. 41). Mandible small, with a large 2-branched palp, one of the branches 2-, 

 the other 4-jointed (fig. 42). Anterior foot-jaws stout, short, 4-jointed, first joint 

 long, the second provided with an appendage bearing a large rounded cluster of curled 

 filaments, and somcAvhat resembling a sheaf of corn in miniature ; third and fourth joints 

 small and armed with a large spiniform and several small plumose setie (fig. 44). Posterior 

 foot-jaws slender and elongate, 6-jointed, the first, second, and fourth joints long, the 

 others very short and bearing a few seta;. The first four pairs of swimming-feet as in 

 Scolecithrix ; the terminal spines are strongly serrate on the outer edge, those of the third
