Pennatula pendula, n. sp. Plate VII. fig. 1 ; Plate VIII. figs. 7 and iU. 



This species, which in some ways resembles P. murrmji, Kolliker, is represented 

 l)y numerous specimens. 



The usual colour of the stalk and rachis is dark red, but in some the rachis is 

 pinkish below, then almost jDure white, and then coral red. The pinnules are 

 usually white, but some are coral red. The autozooids are red, their tentacles 

 white, the siphonozooids are yellowish. 



The axis is cylindrical above, quadrangular below ; at the lower end two of 

 the angles are produced into wing-like expansions. 



The translucent pinnules, of which there may be over fifty pairs, are elongated 

 triangles or lanceolate. The calyces have eight projecting spines. 



The siphonozooids are in two rows on the pararachidial surfaces. 



As there are many specimens, we give several sets of measurements to show 

 quantitative differences.

 Pteroeides triradiata, u. sp. 



At the base of the stalk there is a slight swellins;, 8 mm. in lenotli and 3 mm. 

 in breadth, from the end of which the liare axis projects and ends in a hook-shaped 

 portion. 



At a distance of 15 mm. from the end of the stalk a large .swelling (4 "8 mm.
