CRUSTACEA MALACOSTRACA. 



during the last tweuty >ears or more; at East Greenland, Iceland and the Faeroes it has never 

 been found. 



Distribution. This so easily recognised species has ujj to the present never been found 

 elsewhere except at the West Greenland coast. 



Remarks. One of the largest specimen, a female, is 54 mm. long. 



Dr. Doflein writes: "Kroyer scheint nach meiner Ansicht diese Art auf ein etwas abweichendes 

 (verletztes und geheiltes?) Exemplar von H. acnleata begrundet zu haben". The learned author's 

 boldness is displayed on so many different questions that it is quite remarkable. It gives him no 

 trouble to express an opinion in this way on H. microccros, founded by so excellent an observer as 

 Kroyer, though he himself has never seen a specimen of the species, in which the abdomen lacks the 

 very obvious spinous equipment which characterises //. aculeata from all other Greenland species, 

 whilst according to Kroyer H. aculeata lacks but H. microceros has epipodites on the third pair 

 of thoracic legs. Lastly, Dr. Doflein opines that Kroyer has founded //. microccros "auf ein . . . 

 Exemplar", whereas Kroyer "has found some few specimens", and indeed in the Latin diagnosis speaks 

 of "Antennae. . .marium" in contrast to the antennae "in feminis", and must therefore have seen more 

 than one specimen. From this and several cases mentioned previously it appears, that the learned 

 carcinologist Dr. Doflein requires even less for his reading of an author he quotes or whose judgment 

 he controverts than he does for a species, e. g. S. groenlandica, to make it "somit cirkumpolar".

Occurrence. The "Ingolf" has taken this species at 14 stations. These all lie in the Northern 

 Ocean, within an area which is bounded to the east by a line from Jan Mayen to the Faeroes and 

 extends also so far to the west that it passes north round the north-eastern end of Iceland and from 

 there southward round East Iceland to the Fteroes. The stations are as follows:
