ALCYONARIA. 319 



Telesto (Carijoa) trichostemma, WRIGHT and STUDER. 



This species is represented by one specimen, which agrees with the description 

 given by WRIGHT and STUDER. 



The spicules are of two distinctly marked types : 



(1.) Long slender spicules with few lateral processes, often bifurcated at the end ; 



(2.) Strong, relatively broader spicules, with prominent lateral processes which 

 interlock and form a felted covering. 



They measure, length by breadth in millimetres, as follows : 



(1.) 0-3 X 0-02; 0-28 X 0'019 ; 045 X 0'012 ; 0'26 X O'OH. 



(2.) 0'2 X 0'03; 0'25 X 0'02 ; 0'23 X 0'03. 



The distance between the bifurcations at the ends of the spicules of type (1) often 

 measured 0'02 millim. 



Locality : Patani (Siam). This was one of Mr. NELSON ANNANDALE'S three speci- 

 mens already referred to. 



SECTION II. : PENNATULACEA. 



FAMILY: UMBELLULID^E. 

 Umbellula, sp. 



The collection included* a small specimen, doubtless a young colony, of a species of 

 Umbellula. As the specimen is a poor one, we have not studied it in any detail. 

 We may refer to our forthcoming report on Professor ALCOCK'S " Investigator " 

 collection of deep-sea Alcyonacea from the Indian Ocean, which includes numerous 

 Umbellulids of large size. 



FAMILY : VIEGULARIID^E. 



Virgularia multiflora, KNEE. 



The specimen representing this species is fragmentary. It consists of a piece of the 

 rachis, which seems to come from the lower portion of the colony. It measures 

 51 millims. in length and has 20 pairs of pinnules. The pinnules are crescent-shaped, 

 3 millims. in breadth and 2 millims. in height, with 11 polyps _on each. The axis is 

 white, almost perfectly cylindrical, with a pitted appearance on the surface and with 

 a diameter of 1 '2 millims. The specimen agrees very well with the description given 

 by KOLLIKER. The following comparison will show the close similarity between the 



specimens : T , .. ,
