Tin- rding to S.us and Stappers, known only from depths between »> and so fathoms, 



tints .1 pronounced shallow-watei form. Tin- following list oi localities shows nearly every desirable depth 



to .m«l 582 fathoms, ami even that a couple oi specimens from nearly 1200 fath .11 <1 to 



tin- 1 have spent a good deal of time in search for any reliable character, by which it would In- possible 



the specimens from more than 50 or 100 fathoms to another species, but without result . In tin- cara] 

 the antennulse, the thoracic legs oi firsl and second pairs, and tin- uropods some \ ariation in minute particulars 

 could be found, but no real difference indicating the possibility ol dividing the form into two species. ' >nly 

 one feature may be noted, viz. that the 2 specimens from Stat. [5, [62 fath., 4 of the 5 specimens from Stat. 



fath . and the majority of, bu1 not all, specimens from Stat. 32, 318 fath., have some or several saw- 

 teeth on the dorsal edge ol first and second tree thoracic segments, while such teeth are absent in the 2 spec- 

 imens from Stat 28, 420 lath., the 2 specimens from Stat. 12(1. 2.1 | fath., the 2 young males from Stat. 24, 

 1 100 fath., ami in specimens from all places with the depth less than 200 fath. The existence of such dorsal 

 teeth on the anterior thoracic segment*- is consequently to lie regarded as variation in specimens from con- 

 siderable depth. 



It may he mentioned that second joint of the exopod in the uropods is always at least rather long, 

 but frequently not .,- long in proportion to first joint as shown by Sars. Stappers states that he lias found 4 

 lanceolate appendages on the ischium of third pair of thoracic legs in the adult males, and that these append- 



shotter than in the other lioreal 01 arc tir forms examined l>v him ; this observation agrees completely 

 with males from ( tnundar Fjord examined by me, and it is mentioned here, because G.O. Sars in 1865 has an- 

 other statement and in 1900 a third statement, both consequently wrong, 

 currence. Taken by the "Ingolf" at 8 stations.
