that I identify the completely macerated stalk shown in PI. VI., 

 fig. Ô, as that of the present species. The liranched state is to 

 be accounted for by the intercanal or intercanals that go right 

 through the sponge at the junction of the l)ody with the stalk. 

 The figure just cited will give a good idea of the manner in 

 which the excurrent canals traverse the stalk. 



I may now add some remarks concerning certain individual 

 specimens. 



The largest specimen I have seen (O. C No. 40B4) was 

 020 mm. high, the body measuring fully 250 mm. in greatest 

 breadth. 



The typically shaped specimen (O. C. No. 108), shown in 

 PL VI., fig. 6, measures 247 mm. in height and 190 mm. in 

 greatest breadth. Htalk, about 90 mm. long. Osculum, 120- 

 140 mm. in diameter. Gastial cavity not deeper than 100 mm. 

 Greatest thickness of body- wall (as measured between two points 

 in the gastral and the general external surface), 90 mm. or 

 more. 



Another exquisitely preserved specimen — that depicted in 

 PL VI., fig. 7, in a longitudinal section (8. C. M. No. 365, 

 from (lutside Okinose)— is smaller. Total height IIT) mm. 

 Breadth at the osculum, oO mm. Greatest l)readth, 74 mm. 

 Stalk, ahout (>0 mm. long and ^-14 mm. })r()ad. Gastral cavity, 

 40 mm. deep. 



An individual with an uiuisually widely expanded calyx had 

 a lireadth of 300 mm. and a height of 2öO mm. 



Of special interest are the two smallest specimens I have 

 had at my disposal (S. C ^l. Nos, 484 & 485, shown in the 

 appended text-figure 2). The smaller of the two (Ä) is about
