CRUSTACEA MALACOSTRACA. III. 1^9 



most four years before his description was written, and that therefore the colour had faded consider- 

 ably; Tattersall said in 1911: "Farbe schwarz". — Stephensen wrote: "The exopodite is evenly rounded, 

 not indented ; "exopodite" is decidedly an error instead of "epipodite", and when Walker figured the 

 distal part of the inner margin of the epipod of the maxillipeds as deeply and irregularly serrate it is 

 certainly erroneous; such serration is not found in any species of the group Eurycopini. — I do not 

 quite understand Stephensen's statement on the palp of the maxillipeds: "the median edge of the 4. 

 joint being somewhat concave" in M. Tjalfiensis ; judging from his figure he ought to have said 

 "third joint", as this joint has on his figure the inner margin somewhat concave; unfortunately his 

 figure is as to this point either incorrect or shows an individual variation, as I have examined the 

 maxillipeds of some specimens, two among them of his material, and found the inner margin of third 

 joint convex, as shown on my drawing (fig. 7 a), consequently as to this point agreeing with Walker's 

 figure of E. Murray/. That, as Stephensen pointed out, there is a difference in the small terminal joint 

 of the maxillipeds between his species and Walker's figure is true, but it is easily seen that Walker's 

 figures as to such minor points are not accurate, and his text contains nothing on that feature. — 

 Finally Stephensen wrote: "Furthermore, the metasome of M. Murrayi is stated as having a blunt carina; 

 no trace of any such is visible in the specimens here concerned." The upper surface of the abdomen 

 is so thin-skinned that it generally is irregularly impressed or somewhat folded, and no keel is visible, 

 but on a well preserved abdomen I observed a feeble, rounded median keel. For the rest, Stephensen 

 and Walker use the term "metasome" for very different sections of the body, as Walker wrote (p. 228) : 

 "The first of the last three segments (metasome) with a large oval tubercle on each side of a central 

 cleft." On well preserved specimens I find a longitudinal median cleft not only on the first segment 

 but on the anterior part of the two other segments of the so-called "metasome" — on sixth and seventh 

 thoracic segments the cleft widens posteriorly to be a triangular depressed area — and the surface 

 at each side of the cleft is raised like a badly defined blunt keel or oblong tubercle. It is seen that 

 Walker wrongly applies the name "metasome" used by Sars in his Account, and Stephensen has followed 

 Sars. — I have now analyzed all the differences pointed out by Stephensen as distinctive characters 

 for his Munneurycope Tjalfiensis, and it is absolutely certain that it must be cancelled as only a sy- 

 nonym. But it may be added that most of Stephensen's figures in 1915 are fairly accurate, and quite 

 sufficient not only for recognizing the species, but for judging of its peculiarities and affinities. 



Occurrence. E. Murrayi has not been gathered by the "Ingolf", but at a single locality by 

 the "Tjalfe" and at five places by the "Thor".
