CUCUMARIA CROCEA.

In the succeeding memoir by Prof. MacBride and Mr. Simpson there will be 

 found an interesting account of the brood-pouches and young of this form. It was 

 taken at Coulman Island, 100 fms., and on various dates at Winter Quarters down 

 to 41 fms. 



Cucumaria laevigata.

The characters of these two species have been fully discussed by Prof Ludwig, 

 and it is quite unnecessary for me to enter again on the subject. 

 Taken in Winter Quarters to 41 fms. and in McMurdo Bay. 



Several distorted Cucumariae and some young were taken at various dates while 

 at Winter Quarters, and at 78° 25' 40" S., 185° 39' 06" E. 



PSEUDOPSOLUS FERRARI. 



(Plate v., fig. 3.) 



It is unfortunate that this new species should be represented by a single specimen 

 only, but there is no doubt that it is unlike any form that has as yet been described. 



Tentacles ten, two much smaller than the rest ; trivial pedicels in three complete 

 longitudinal series ; dorsal perisome devoid of large scales or grains, flexible and soft 

 to the touch, and having only a few trellis-like spicules. There are some distinct 

 pedicels scattered on the dorsal surface. 73 mm. long, 32 "5 mm. greatest width. 



The important diflerences between this species and the only form belonging to the 

 genus which has yet been described are of varying value ; the distinctness of the dorsal 

 pedicels is of great significance, for their presence in P. macquariensis is so inconspicuous 

 that Prof Dendy denied their existence, on which Prof. Ludwig has remarked 

 " Zu einer Entschuldigung will ich aber gleich hinzufiigen, dass die dorsalen Fusschen 

 sehr gering an Zahl und sehr retraktil sind, sodass sie sich der Beobachtung leicht 

 entziehen konnen." f 



The spicules are more delicate and trellis-like in the new species, and there is a 



* In my ' Southern Cross ' Report I cite Wyv. Thomson as the first author of the combination " Cucumaria 

 crocea'' ; he wrote Cladodactyla crocea in 1876 (not 1878, and not on p. 55) ; as all my blunders were made by 

 Dr. Lampert in his " Seewalzen," I stand convicted of neglecting the legendary advice of the venerable gentleman 

 who was once President of my College at Oxford.
