slightly imbricated. In the upper part of the calyx the spicules have the form 

 characteristic of the genus, rlz., a needle-shaped shaft springing from a divaricate 

 poi'tion, the basal part having 2-6 warty processes, the spine part sinnoth. At the 

 base of each of the tentacles there are two rows of slender warty needles, includ- 

 ing acute angles at the distal extremity. There h- no cnlhirct.

Colony bush-like, twig ends usually club-shaped. Cffinenchyma thick, 

 especially on the twigs, bearing, superficially, large much curved spicules with 

 long processes. Beneath these there are similar smaller spicules. Verruc?e 

 hardly projecting, opening surrounded by a wreath of long smooth spines on an 

 expanded ragged basis. The spicules of the coenenchyma form two not very 

 definite layers. Tn those of the upper layer very strong thorny processes spring 

 from about the middle of large spindles which often acquire a 3- or 4-rayed 

 or irregular T-like appearance, as if two were joined by their convexities. 

 The spicules of the inner layer are much smaller. At the free end of the verruca 

 there are long, vertical, projecting needles ; a second ring more irregular and 

 more divergent is found lower down ; these sit upon an expanded basal part 

 which bears small warts. The operculum consists of small, straight or slightly 

 curved rods and spindles which lie more or less obliquely in two rows, one on 

 each side of the middle line of the dorsal surface of each tentacle ; the tips of 

 the triangles thus formed usually reach to the middle of the tentacles. There 

 is no collaret.

Note. — This species comes nearest to E. indomalarxensis, Ridley, but is 

 distinguished not only by its brownish-red colour but also by the arrangement 

 of the spicules, by the shape of the verrucce which are not only not stalked but 

 hardly protrude, by the mode of branching which is generally dichotomous at 

 the end, and by the form and arrangement of the ctenenchymal spicules. 



Correction. — The specimen described as Echinonmricen ceylonen><is (Thom- 

 son and Henderson, " Ceylon Pearl Oyster Fisheries Eeport," p. 292. Plate 

 VI. fig. 6), should have been referred to the genus Acamptogorffia. The two 

 genera are closely allied, but as we have indicated above each has its distinctive 

 spiculation.
