56 DR. R. V. WILLEMOES-SUHM ON SOME ATLANTIC 



That they must be very close appears already from what we have said ; and among the 

 Eryontidse this new deep-sea genus must take its place. The Eryontidse, now consisting 

 of two genera, must either form a new family intermediate between the Astacidse and 

 Palinuridae, or be united with the latter. 



During our cruise in the Atlantic we got deep-sea animals (i. e. from more than 350 

 fathoms ; stations where only Eoraminifera-shells have been got are not included) from 

 67 stations. After every haul a list of these animals, as much specialized as our know- 

 ledge of the thing allowed us to do, has been put down by me in the so-called Station- 

 book. As it might be of some interest to know how often the different groups of animals 

 have been got, I have made the necessary additions, and shall terminate this paper by 

 giving the results as far as Crustacea are concerned. According to this, 



Cirripedia have been got 9 times. 



Ostracoda 1 time. 



Amphipoda 7 times. 



Isopoda 6 „ 



Cumacea • . . 2 „ 



Stomatopoda 1 time. 



Schizopoda , 12 times. 



Decapoda Macrura 22 „ 



Decapoda Brachyura 11 „
