CRUSTACEA MALACOSTRACA IV. 27 



22. Eudorella sequiremis n. sp. 

 (PI. II, figs. 3 a— 3 d.) 



Female (adult and subadult). Body with a moderate number of fine liairs. Carapaee (fig. 3 a) an- 

 teriorly almost as in E. intermedia ; the antennal notch normal, and just below it, between it and the somewhat 

 short unarmed part one tooth or less frequently two teeth; the margin above the notch is serrated incon- 

 spicuously more than half of its length, with a few of the upper teeth somewhat large, but the majority rather 

 small and not always easily seen; the lower margin of the carapace is anteriorly curved a good deal upwards. 



The antennulae normal (fig. 3 a). First pair of legs (fig. 3 b) with the propodus a little longer than, 

 or only about as long as, the carpus and less than twice as long as the terminal joint. Second pair of legs 

 (fig. 3 c) differ from those in E. intermedia in having the carpus conspicuously longer and much thinner than 

 the merus, and carpus is as long as, or slightly shorter than, the two distal joints combined; terminal joint 

 rather narrow. -- Uropods (fig. 3 d) as long as the two distal segments combined; peduncle about as long 

 as the rami, with 4 spines on the inner margin; exopod with 2 or 3 seta; on the upper side and none on the 

 outer margin; the endopod, which does not overreach the exopod, has its first joint two and a half times 

 as long as the second, with 5 spines on the inner margin; second joint has on the inner margin 3 spines, on 

 the end the thick, rather long spine and a very long seta. 



Length of an adult female 4.5 mm. 



Remarks. E. cequiremis is instantly distinguished from all other northern species excepting E. 

 arctica in having the endopod of the uropods not longer than the exopod ; from E. arctica and the other forms 

 excepting E. intermedia and E. hirsuta G. O. S. it is separated in having the major part of the front margin 

 of the carapace above the notch serrated, but the serration extends less upwards than in E. hirsuta. 



Occurrence. Taken by the "Ingolf" at a single deep station in the warm area. 



Davis Strait: Stat. 36: Lat. 6i°5o' N., Bong. 56°2i' W., 1435 fath., temp. 1.5"; 7 specimens, among 

 them 2 females with marsupium, 1 subadult female and 2 young males. 



Eudorellopsis g. o. Sars. 



Of this genus 2 species are observed in our area; both were previously known from West Greenland. 

 It may be possible that the North American species E. biplicata Caiman can in the future be discovered at 

 West Greenland or Iceland.
