THOMSON AND MACKI^^NON— STOLONIFERA, ETC. 201 



sp. n., was almost covered with Palythoids, which, as was stated, rather obscured the 

 real appearance of the colonies. Although these specimens differed in some respects 

 from the description oiP.fruticosa given by Wright and Studer, an acquaintance with 

 a larger number of specimens, and especially with those in this collection, leads us to 

 merge P. indica in P.fruticosa.

There are several small branching pieces and one almost complete colony, which is 

 much overgrown by an encrusting sponge. The height of this specimen is 7 cm. It 

 gives off five pendulous "branches," two of which are nearly 6 cm. in length. The 

 polyps are arranged on the four sides of the branches, from which they project to a 

 height of 2-2'5 mm. 



Locality. Cargados Carajos, 28 fms., 30 fms.

Genus PENNATULA. 



76. Pennatula sp. (Plate 9. figs. 9 & 11.) 



Two small but complete colonies, 5*5 cm. and 3'5 cm. in height respectively. The 

 larger specimen has fifteen pairs of pinnules, the other has about six pairs. The 

 greatest number of autozooids borne on a pinnule is three. We were unable to see any 

 siphonozoids. 



The fully developed autozooids are from 2-4 mm. in length. The colour of the stem 

 is a bright orange-red, fading into white on the lower parts; the polyps ai'e lemon- 

 yeUow. In some features, e. g. of the spiculation of the autozooids, these specimeus 

 bear a strong resemblance to Pennatula pendula, Thomson and Henderson, of which 

 they may be young forms. 



Locality. Seychelles, 37 fms. 



Pennatula pendula was found at the Andamans.
