596 REPORT OF COMMISSIONER OF FISH AND FISHERIES, [94] 
identification, A few species obtained in 1884 are also included in the 
list. * 
Atolla Verrillii Fewkes, sp. nov. 
The genus Atolla was described by Heckel in his report on the a 
sea medusz of the “‘ Challenger,” from the Antarctic Ocean, between the 
Kerguelen Islands and Melbourne, and from St. Mathias Bay, Pata- 
gonia. 
Our species was collected in the following localities :

The genus is represented by eight specimens, three of which are over 
45™™ in diameter. The “Challenger” collected five specimens. Our 
species is very closely related to the Antarctic one, A. Wyvillit Heeck. 
The depth recorded for A. Wyvillit is 1,950 and 2,040 fathoms. Our 
species ranges from 373 to 2,369 fathoms. My largest specimen, a little 
over 45™™ in diameter, although smaller than Heckel’s largest (66™™) 
has twenty eight tentacles, marginal sense-bodies, and marginal lobes 
before bifurcation, while his has but twenty-two. 
Nauphantopsis Diomedee, gen. et sp. nov. 
A new genus, Nauphantopsis, one of the most important collected by 
the “Albatross,” resembles Nauphanta in the sculpturing of the exum- 
brella, but while the latter has sixteen marginal lappets, Nauphantopsis 
has thirty-two; Nauphantopsis has thirty-two deep furrows across the 
corona; Nauphanta has sixteen deep and sixteen shallow coronal incis- 
ions; Nauphantopsis has twenty-four tentacles and eight sense-bodies, 
which are very imperfect. Nauphanta has eight tentacles and eight 
sense-bodies. Three tentacles are therefore side by side on the rim of 
the former, alternating with the sense-bodies. The single specimen was 
found at station 2038, in latitude 38° 30/30’ N. and longitude 69° 08/ 
25” W., in a depth of 2,033 fathoms. 
This genus is morphologically one of the most valuable of the collec- 
tion, and, like Nauphanta, probably belongs to the deep-sea fauna. It 
connects the taney of Collaspidx, of which Atolla is one of two mem- 

“In most cases it is impossible to say whether the novel Sorin of medusz taken in 
the trawl and trawl-wings are inhabitants of the bottom waters or the surface, or of 
intermediate depths. Eventually those that belong to the surface-fauna will doubt- 
less be taken in the surface-nets, but this will require much more extensive collecting 
of the surface animals than has yet been attempted.
