CRUSTACEA MALACOSTRACA. (yj 



Distribution. The species has several times been taken at Halifax, Nova Scotia, 26 to 57 fm. 

 (S. I. Smith), in the St. Lawrence estuary, 30 to 70 fm. (Whitea\es), at Labrador (Packard), lastly in 

 the Bering vStraits, the Bering Sea over towards America and at Kamtschatka and in the Sea of 

 Ochotsk, 16 to 100 fm. (Mary Rathbun). 



Remarks. Doflein in "Fauna Arctica" has placed S. Mac/lcn/a Kr. as a synonym to ^'H. phippsi 

 Kroyer"; on the following page (p. 333) under 5. spiiiiis he writes however: "Betrachte ich aber das 

 gesamte Material, so kan ich so viel Uebergange zu H. phippsi feststellen, msbesonders zu den als 

 turgida and macilenfa von Kroyer als besondere Arten beschriebenen Formen von pliippsi, dass ich 

 glaube, es handelt sich nur um eine Art, welche dem Prioritatsgesetze gemass den Namen H. 

 spinus Sow. tragen muss. Diese Annahme wird auch durch die ganz gleichartige Verbreitungsweise 

 der fraglichen Species unterstiitzt". That H. phippsi Kr. was the male, H. turgida Kr. the female of the 

 same species had been made out many years before Doflein's work, but when he wishes to include 

 H. turgida Kr. and H. macilenfa Kr. under H. spinus Sow., that shows great lack of knowledge of his 

 subject and great hardihood. And the support given by the "gleichartige Verbreitungsweise" to the 

 view that there is here only a single species is indeed a broken reed, as the three species have a very 

 different distribution: .S'. macilenta is only known from West Greenland and the waters on each side 

 of the most northerly parts of North America, whilst both the other si^ecies are found for example on 

 the northern parts of Europe, further S. turgida is certainly more arctic in its distribution than S. spinus.

Occurrence. The "Ingolf has brought home this species from two localities. 



Baffin Bay: St 33: 67°57'N. L., 55° 30' W. L., 35 fm., temp. o-8°; 2 spec. 



Davis Straits: The mouth of Ameralik Fjord at Godthaab, 5 — 70 fm.; i spec. 



I have given in Malac. Groenl. a large number of localities for this species; the most northerly 

 was at 8i°44'N. L. at Grinnell Land (Miers), also along Greenland itself from 78° 17' to 6o°43'N. L.; 

 the species is stated to be common in from 2 — 4 fm. and out in ca. 25 fm., it was taken some few 

 times in depths from ca. 50 to 60 fm., but two statements of its occurrence in 100 and 200 fms. at 

 Sukkertoppen I considered "very doubtful", and I believe I am now able to say that 100 fm. is 

 probably correct, 200 fm. certainh- incorrect. Later discoveries have not extended this know'ledge ; 

 Ohlin and Ortmann show that the species is common between 76° and 79° N. L, in 5 to 45 fm. — At 

 East Greenland the species has been taken at Tasiusak, 65° 37' N. L., 37° 34' W. L., 5 — 19 fm. and in 

 the eel-seine, 9— o fm. (Amdrup Exp. and Kruuse), and at Hekla Harbour in Scoresby Sound, 70°27'N. L.,
