888 PROF. S. J. HICKSON ON THE 



Hydropliytum flabellate in growth. There is no statement to 

 the effect that the branches anastomose. No record of size 

 beyond the statement that it is smaller than L. moseleyi. 



Colour : bright crimson, with the compressed forked tips palei\ 



Surface minutely reticulate. Grooved spines arranged in rows, 

 but not in clusters, on both sides of the branches, all turned away 

 from the apex of the branch. 



Gasteropores without a lip, 0-22 mm. in diameter (in the Chili 

 specimen). 



Large dactylopores 0-09 x 0*2 mm. 



Small dactylopores 0'08 mm., without any lip or collar. 



Errina (Labiopora) moseleyi Ridley. 



The single specimen of this species was found at Port Rosario, 

 S.W. Chili, 2-10 fathoms. 



Hydrophytum flabellate in growth. Anastomoses frequent. 

 95 mm. in height x 135 mm. in width. 



Colour : " vermilion." 



" An anterior clearly distinguishable from a posterior surface, 

 by the development on it of numerous tubercles, chiefly in the 

 terminal branches, which are very slightly indicated in the latter." 

 Surface minutely reticulate. Grooved spines not arranged in 

 definite rows nor in clusters. 



Gasteropores without any lip, 0-32 to 0*35 mm. in diameter. 



Large dactylopores 0*1 to 0-14 mm. in longitudinal diameter. 



Small dactylopores without lips or tubercles, of about the same 

 size as the large dactylopores. 



Errina (Labiopora) aspera Linn. (PI. XCY. fig. 6.) 



I have examined the type-specimen of this species in the 

 British Museum on which Gray (1) founded the genus Errina. 

 There can be no doubt that the afiinities of the species with the 

 genotype of Labiopora are closer than they are with Moseley's 

 Ei-rina labiata. It belongs to the Labiopora^ and not to the 

 Errina group of species. 



One of the colonies in the British Museum is 80 mm. in height 

 by 85 mm. in width. It forms a flabellum with a clear difi'erence 

 between the anterior and posterior surfaces. The branches 

 terminate in fine points and do not anastomose. The branches 

 are about 3 mm. in diameter at a distance of 3 mm. from the 

 apices. The surface is minutely granular. The grooved spines 

 sometimes occur in clusters, but when solitary the grooves are 

 turned away from the apex of the branch. There are a few small 

 dactylopores without spines and some with small or rudimentary 

 spines. This specimen was dredged ofi" the coast of Sicily. 



A little while ago a specimen of a Stylasterine coral was sent 

 to me by the late Mr. John Morgan of Worthing. It was 

 purchased in a sale and there was no record of its locality. 



At first I thought it should be placed with the other specimens
