to 2'o mm. in lengtli and ()"15 mm. in breadth, and are arranged irregularly on 

 the larger branches. 



Canal-wall spicules : In the canal walls there are spindle-s and three-rayed 

 forms, the spindles often bifurcated at one end. 



Colour ; The principal branch is yellowish ; the smaller branches and twigs 

 deep orange ; the polj^ps white. 



Locality ; Andanians (J. Wood-Mason). 



Dendronephthya, sp. (?) 



This is a fragment, rigid in character, cylindrical in shape, and from it 

 rise numerous smaller branches on all sides, which by repeated division give 

 rise to the polyp-bearing twigs. 



The polyps are arranged in small groups of about six, and are placed 

 at a very obtuse angle on the stalk which measures up to 2 mm. in length. 

 They are somewhat conical in shape, and measure 0'66 mm. in height and 072 

 mm. in width. The polyp-spicules are arranged in eight double rows, in each 

 lateral row there are from six to eight pairs of spicules, one of the second upper- 

 most pair being much larger than the others and projecting. The si)icules are 

 spindles either curved or straight, and average 0"24 mm. in length ; the upper 

 may reach a length of 0(3 mm. and project 0"24 mm. beyond the polyp. They 

 bear simple thorns which are directed obliquely towards the tip on the project- 

 ing part of the larger spicules. 



The Stutzbiindel is well developed, one of the spicules projecting for a 

 considerable distance (about 1 mm.) beyond the polyp, and reaching a lengtli 

 of 3 3 mm. 



Cortical spicules : In the stem the spicules are spindles which bear numer- 

 ous regularly arranged, blunt, rough to branched Avarts. They vary from 

 0"42 to 3"(j mm. in length and from 0'09 to 027 mm. in width. There are, in 

 addition, numerous smaller spindles with fewer warts. They form a network 

 on the principal portion, but are more longitudinally arranged on the smaller 

 branches and twigs. 



Canal-wall spicules : In the stem there are spindles. 



Colour — The stem or branch is white, the smaller branches yellowish-white ; 

 the polyp-stalks reddish ; the polyps red ; the tentacles white with red spicules 

 on the aboral surface. 



Locality : Off Ganjam Coast, 28 to 30 fathoms. 



Dendronephthya, sp. (?) 



This is only a fragment of a colony. It measures 2 "5 cm. in height and 



lo cm. in maximum width.
