I I TKAXONIDA. 35 



To-wont (31. p. 70) records a new apedei, Artrinisinti (liaiuu; from Booth-Wandel 

 Island, Autan-tic, apjwrcntly very closely related to A. apollini*. The ' Discovery ' 

 specimen resembles A. diamw in having curved styles of the same length, but they 

 arc narrower ; and the spincd toxa arc much smaller in the first peciefc 



The specimen was dredgetl near Winter Quarters, off Hut Point, '25-30 fms. 



The ' Challenger ' obtained specimens from Kergueleu Island, 20-60 fins. ; and 

 the Danish Ingolf Exp. from East Greenland, depth ? , Lundl)cck.

The single specimen, which has been broken off from its attachment, is massive 

 below, but divides above into two cylindrical lol>cs. The colour is pale brown in spirit. 



A few small oscules, evidently much contracted, occur at the summits of the lotas. 

 The surface is finely villous, from the presence of the projecting point* of fan-like 

 lines of oxeas. 



Here and fhere the flesh has become macerated away, leaving fluffy lines of fine 

 skeleton fibres. 



The only difference worthy of mention that I can find between the Northern and 

 Antarctic specimens is the absence of the placocheles or isochclac palmatac with broad 

 shafts. I can only discover two kinds of isochclae palmatae. The sigmata occur 

 in many sizes. Some have bifurcated terminations, as figured by Fristedt, and 

 Lundl>eck. 



Spicules. Megasclerea Styles 671 x 18 M, fusiform, straight, occasionally with 

 head slightly bent 



The styles in Carter's type from Faroe are almost identical in character. 



Microscleres. Larger palmate isochelae, 43 M long, 9*75 M broad, length of 

 teeth, 16 M. 



Smaller palmate isochelae, 1 8 M long, 4 M broad. Sigmata, numerous, varying from 

 small up to very large sizes. 



The distribution of this species is very interesting, occurring as it docs in Arctic 

 and sub- Arctic waters ; then, as an intermediate link between Arctic and Antarctic, in 

 deep water off the Azores. 



The specimen was dredged near Winter Quarters, in McMurdo Bay, 20 fms. 



This species has been found (l) Between Scotland and Faroe, 440 fms., 

 Carter; E. Coast of Greenland, 254 m. (140 fms.), Fristedt; off Iceland, Denmark 

 Strait and Davis Strajt, 44-553 fms., Lundbcck ; Azores 2,252 m. (1,196 fms.), 

 Topsent.
