412 Rev. A. M. Norman on new Crustacea Anvphipoda. 



the wide extremity of the wrist, in a central hollow between 

 two lobes. Pleon usually (but not invariably) having a hump 

 on the back of the fourth segment. Telson squamiform, semi- 

 elliptic, cleft almost to the base, cleft narrow, not widening at 

 the extremity. Urojpods : first scarcely equaUing second ; last 

 having two flattened, one-jointed, equal rami ; inner margin 

 of inner ramus with three short blunt spines, its extremity 

 and both margins of exterior ramus setose. Length -fV inch. 



Goes remarks on this species : — " Ex abysso ad Aukpad- 

 lartok Groenlandias copiam magnam retulit Torell speciminum 

 valde robustorum et oculis quatuor, duobus in vertice, duobus 

 in angulo infero-laterali antico capitis insignium — ceterum 

 cum nostra plane congruentium." My Northumberland spe- 

 cimens agree with those from Greenland in having ^wr simple 

 eyes. The number of eyes, therefore, would not seem to be 

 constant ; but there are ample grounds for separating the genus 

 Haploops from Anvpelisca. 



First found by me in deep water off Berwick, and seven 

 miles off Tynemouth, Northumberland, in 1862, and again 

 dredged in 1866 in the Minch. 



Genus Tessaeops, n. g. 



Eyes four — two (large, compound) situated above the origin 

 of the superior antennae, and two (nearly simple) below the 

 others, at the base of the superior antennae. Superior antennm 

 furnished with a very slender secondary appendage. Both 

 pair of gnathopods simple, not subch elate. Jjast pereiopods 

 short, stout. Pleon having dorsal margins of segments toothed. 

 Telson squamiform. Last uropods two-branched.

Head produced. Upper eges ovate, large ; lower eyes (in 

 type specimen) consisting of two lenses. Superior antennce 

 having each joint of the peduncle shorter than the preceding 

 one ; flagellum composed of ten, secondary appendage of five 

 very long articulations ; the basal articulation of the flagellum 

 longer than either of the last two joints of the peduncle ; the 

 secondary appendage is remarkably slender at the base, and 

 equals the first four articulations of the flagellum in length. 

 Inferior antennce considerably longer than the superior ; last 

 joint of peduncle equal to two-thirds the length of the penul- 

 timate, flagellum of about the same length as the peduncle.
