554 Piof. J. A. Thomson ay\cl Mr. W. D. Henderson on 



Juncella elongata (Pallas). 



Several brick-red fragments ajjree well uith this species, 

 but there is a trace of a longitudinal bare streak and ridge ; 

 the spicules are spiny spindles, double clubs, and double 

 stars; no "triple stars'^ were found. 



Locality. Bay of Bengal, 88 fath. 



Order STELECHOTOKEA. 



Section I. A s i p h o n a c e a. 



Family Telestidae. 



Telesto rubra, Hickson. 



A single specimen, apparently a complete young form, 

 with a spreading base and one branch. The polyps, which 

 measure 25 mm. in height, arise at right angles to the stem 

 and are arranged on the four sides in such a way that they 

 seem to form a spiral. In the ridges on the axis, in the 

 minute quantity of horny matter, and otherwise the specimen 

 agrees with Hickson's description. 



Locality. Andamans, 120 fath. 



Telesto Arthuri, Hickson & Hiles. 



A white colony closely resembling T. Arthuri, e. g. in 

 having no grooving, in there being no axis, in the arrange- 

 ment of the polyps in short spirals or in whorls and singly, 

 and in the shape of many of the spicules — spindles straight 

 and curved, triradiate, and quadriradiate forms. It differs 

 in not having the secondary polyps so closely crowded. It 

 is evidently a young form. 



Locality. Station 232, 430 fath. 



Section II. P e n n a t u l a c e a. 

 Family Protocaulidae. 



Protocaiilon indicum, sp. n. 



Three complete specimens, with short thin stalk, long 

 rachis, opposite biserial polyps, quadrangular axis, and no 

 spicules. The larger zooids are sexually mature. 



Locality. Station 23!), 55 fath.
