ject beyond the polyp-head when the latter is retracted. These spindles average 

 about 0-33 mm. in length, the longest reaching 0-63 mm. On the aboral surface 

 of the tentacles two rows of thickly crowded, flat, irregular spicules are present, 

 having an average length of 0'06 mm. ; they may have a few teeth at their edges 

 or they may be perfectly free of these except for the presence of one tooth or 

 spine near one end. 



The Stiitzbiindel is well developed on most of the polyps, one or more of 

 its spicules projecting. One may reach a length of about 4 mm. and project a 

 distance of r2 mm. ; if a second projects it is for a much shorter distance. 



Cortical spicules : (a) The stem contains spindles, from 0'18 to 2-5 mm. 

 long, from 006 to 018 mm. thick, either straight or curved, with long, prominent, 

 smooth or branched thorns ; a number of small flat spindles and branched 

 spindles, which have a stringy appearance and have a few simple spines or teeth 

 on the edges ; a few large three-rayed forms and long spindles with more 

 numerous and blunter spines. These long spindles reach a length of 3'3 mm. 



(h) The stalk contains spindles 0-33 mm. in average length, irregular 

 branched and star-shaped forms. These have numerous large branched spines 

 which may reach a length of 0'12 mm. There are also spherical forms with 

 prominent spines projecting on all sides. 



Canal-wall spicules : In both stem and stalk, spicules seem to be quite 

 absent, except for the presence of a few minute corpuscles in the stalk canal 

 walls. 



Colour — Stalk and flattened lower branches whitish ; stem and other 

 branches yellowish ; terminal twigs and polyp-stalks red ; polyps white or 

 yellow. 



Locality : Gulf of Martaban, 07 fathoms. 



Dendronephthya malabarensis, Henderson. 



This specimen must be classed with the Umhdlatce for the polyps are 

 arranged in small bundles which are all raised more or less to the same level. 

 The colony is small, 28 mm. high, 36 mm. broad, very limp, the branches hang- 

 ing down and completely hiding the stalk. It is flattened in one plane and the 

 growth is more horizontal than vertical. 



The stalk appears very short owing to the position of the lower branches, 

 but it measures 12 mm., almost a half of the total height, and under the 

 low power presents a beautiful appearance due to the presence on the upper 

 layer of white four-rayed spicules which contrast with the yellowish semi- 

 transparent colour of the stalk. 



The polyparium is small, very irregular in shape, flattened in one plane, 

 and more developed in the horizontal than in the vertical plane. It consists of
