terminatino; in a spine, beyond •wliicli the apex of the scale is 

 not proibiccd ; spine on the outer distal corner of the basal 

 joint obsolete. 



Mouth-parts and first and second thoracic limbs not differing 

 in any striking; way from those of the type species. 



Revuiininif thoracic limbs missing, 



Exupods of all the thoracic limbs with the outer distal 

 corner of the basal joint slightly acuminate and the flagelli- 

 form part composed of ten joints. 



Incubatory lamclke of the female, two pairs. 



Telson not quite so long as the last segment of the pleon 

 and once and two thirds as long and broad at its base, where 

 the margins are somewhat expanded; entire and lanciforra 

 in shape, tapering distally to a narrowly rounded apex; 

 di>;tal two thirds of its margins armed with about twcntj'-four 

 short spines, increasing in length towards the apex ; median 

 apical setae absent. 



Uropods moderately slender : inner, about one and a half 

 times as long as the telson, otocyst rather large, with appa- 

 rently no spines on its inner margin ; outer, broken in both 

 specimens. 



Length of both specimens (immature females) 11 mm. 



Locality. Two immature females from S.U. 352, 92 miles 

 S.AV. of Bull Kock, Co. Kerry, lat. 50° 22' N., long. 1 1° 40' W., 

 800 fath., August 1906, Petersen trawl at 750-800 fath. 



This species is readily distinguished by the remarkable 

 structure of the eye, which is one of the most wonderful 

 among the many varied forms met with in Schizopoda. The 

 exact function of the external membranous h dge is not quite 

 clear. In other characters the species is rather closely allied 

 to the type. 



Dactylamblyops goniops, sp. n. 



Carapace covering all the thoracic segments except the 

 last, which is fully exposed ; evenly rounded in front and 

 not produced into a rostral projection ; antero-latcral corners 

 rounded; emarginate behind; cervical sulcus well marked. 



Pleon longer than the carapace, first segment slightly 

 longer than the second, which is subequal to the third, 

 fourth, and fifth; sixth segment rather long, two and a half 

 times as long as the fifth. 



Eyes a little larger than in the last species, set close 

 together and rather suljquadrangular than pyriformin dorsal 

 outline; the digitiform process on the inner and upper face 

 more slender and a little longer than in either the type or
