Simpson — A Revision of the Gorgonellidae. 101 



The diameter of the stem is 4 mm. near the base, but diminishes gratlually 

 to 3 mm. near the tip. The coenenchyraa is thick ; the general colour of the 

 colony is pale yellow ; but the tips of the verrucae and tlie anthocodiae are 

 white. 



The present specimen agrees in detail with llie last, except in the nature 

 of the verrucae (cf. figs. 84 and 85). 



Locality. — Off and oast of Cape Morgan, .36 fms. Bottom : stones. 



A beautiful, complete, simple colony, 22-5 cm. in length ; the 

 coenenchyma is moderately thick and densely granular ; the general 

 colour is a bright orange-yellow ; but the tips of the verrucae and the 

 anthocodiae are wliite, and there are also white streaks throughout the 

 coenenchyma. 



The polyps are distributed in two lateral, longitudinal series ; the bare 

 median tracts are faiily well delined. The number of rows in each series 

 varies from two to four. The verrucae are sub-cylindrical, directed 

 upwards, and adpressed to the stem (fig. 86). Ttie member.s of two adjacent 

 rows alternate with one another so that the tip of one verruca is on a level 

 with Llie base of the next liigiier in tlie adjacent row. The verrucae are 

 about l-2o mm. in height and 075 mm. in diameter. Near the base they 

 are much smaller, more distant, and a few are even sunk into pits in the 

 coenenchyma. The anthocodiae are white ; the tentacles are short, but have 

 a dense aboral armature. 



The canal system is typical and well developed ; tlie two main canals are 

 easily seen when a piece of the coenenchyma is detaciied. 



The axis is slender, flexible, but very calcareous ; tlie surface is marked 

 by longitudinal striae.

A small, complete colony, 15"5 cm. in height ; is almost identical with the 

 last specimen. 



The following dillerences may be noted : — 



(1) The colour is almost brick-red. 



(2) The verrucae are slightly smaller and are more adpressed to the 



coenenchyma. (iJnlh these differences are probably due to greater 

 retraction and to the fact that the colony iUself is smaller.)

In the Littoral Collection of tlie Indian Museum tiiere are four filiform 

 colonies which have the characteristic spiculalion of H. furailn, U) which 

 species we have therefore assigned them. They differ considerably in
