Remarks. — This species is transferred by M. Bonnier to the genus 

 Orchoniene, on account of the shape of the epistomal plate. It is, however, 

 otherwise evidently more nearly i elated to the species of OrchomendJa (Try- 

 phosa Bonnier), though in some points also differing somewhat from the latter, 

 as pointed out in the text. Perhaps it should more ])roperly be regarded as 

 the type of a separate genus. 



Page 74. Orchomenopsis obtusa. 



Of this form, hitherto only recorded from the Trondlijemsfjord, I have 

 subse(iuently taken a single specimen in the Stavangerfjord, at J else, from 

 the considerable depth of 400 fathoms.

EemarJib: — For the reason above mentioned, M. Bonnier lias proposed 

 a new generic name for the sjiecies referred by me to this genus, viz., tiiat 

 of Tryphosella. As, however, I do not agree in this authors view, I propose 

 to retain the above name in the sense adopted in this work. 



Page 76. Tryphosa nana. 



Bemarlcs. — As the Anonyx nanus of Kroyer has turned out to be a 

 different species and identical with Orchomendla ciliata of the author, the 

 present species must of course have a new specific name. M. Bonnier has 

 proposed to name it Tr7/2)hoseUa Sarsi, which, according to the opinion here 

 set forth, should be changed to Tryphosa Sarsi. The distribution recorded 

 under this species ought of course to be transferred to the true OrchomendJa 

 nana (== ciliata G. 0. Sars). The present form has not as yet been observed 

 out of Norway.

Occurrence. — I found this species last summer not infrequently in 

 the Christianiafjord, at Soon, at a depth of 50—80 fathoms.
