372 DISCOVERY REPORTS 



tooth and supra-orbital and pterygostomial spines ; antennal spine very small. Abdominal 

 somite 3 with large, slightly procurved, dorsal spine ; pleura rounded ; somite 6 twice as 

 long as deep. 



Telson three times as long as wide, without lateral spines, and 5+5 terminal spmes 

 of which spine 2 is very large and the inner six quite small. No anal spine. 



Eyestalk shorter than eye, together less than one-third of body length. Peduncle of 

 antennule shorter than eye, less than one-quarter body length; flagella extendmg 

 beyond rostrum. Antennal scale longer than eye; flagellum a little longer than scale. 



Exopod of maxilla very broad and square in front ; endopod with three distinct inner 

 lobes, unsegmented; four endites well developed. 



Maxillipede i endopod of four segments ; coxa large, bearing long setae ; exopod with 

 five terminal setae, and basal enlargement bearing seven setae; epipod large, bilobed. 



Legs I and 2 not chelate. Leg 4 with exopod, endopod lost. Leg 5 lost, but with 

 enlarged base. 



Pleopods present, small. 



Bate's specimen had the rostrum broken, but Ortmann describes his as having it as 

 long as the antennular flagellum, and with eight dorsal teeth, including the tooth on the 

 carapace. Both specimens came from the neighbourhood of Cape Verde. The Discovery 

 specimens are from much farther south and west, and far out in the ocean.

Eretmocaris doUchops Ortmann, 1893, p. 79, pi. v. 

 St. 689. 05° 59' S, 29° 49' W. One specimen. 



Length 11 -6 mm. 



Rostrum small and slender, without teeth. Carapace with dorsal papilla ; no supra- 

 orbital spine ; anterior margin produced into a pointed process above antenna, and lower 

 margin with four teeth. Abdomen without spines, but pleura of somites 3-5 narrowing 

 and rather acute ; somite 6 about three times as long as deep. 



Telson 3^ times as long as wide, without lateral spines; apex with 4+4 spines. 



Eyestalks extremely long, divided by a constriction into two segments, of which the 

 first is the shorter; eye not distinctly marked off from stalk, together nearly as long as 



the body. 



Peduncle of antennule about one-quarter length of body ; flagella longer than peduncle. 

 Antennal scale shorter than peduncle of antennule ; flagellum more than three times as 

 long as scale. Maxillule, palp unsegmented, with five setae. Exopod of maxilla very 

 large, extending far beyond endopod, rather narrow in front. 



Maxillipede i endopod of four segments ; exopod with eight terminal setae, and very 

 slight basal enlargement bearing two setae ; epipod large, bilobed. 



Maxillipede 2, endopod of four segments ; epipod with rudiment of podobranch. 



Legs I and 2 chelate ; carpus of leg 2 very long and slender. No trace of epipods or
