WITHIN THE Gh;NUS DENDROXEPIITHTA. 63 



Locality : — Station 99. 



A second eolon^^ the lai-ger and flattened from side to side, 

 may also be refei'red to D. collaris. Here the polyparinm is very 

 markedly transverse oval. There is no hint of any projection 

 from the anthocodial points (whicli consists of 5-6 pairs en 

 chevron), and the lower cortex shows, among other forms, 

 numerous flattened, spindle-shaped, triradiate, boomerang-like, 

 and irregular spicules, which have not been noticed in the other 

 colonies studied. Yery marked also are the length and strength 

 of the prongs arising from some of the curved spindles, pseudo 

 clubs, and irregular multiradiate bodies. 



Deduction : — If one disregards the detail of growth on which 

 Kiikenthal partly bases the group collaris, namely that the 

 hemispherical bunches are quite supei-ficial, one should place 

 D. collaris close beside D. hahereri, which has more, though 

 similar, spicules in its anthocodial points and a different kind of 

 spiculation on the cortex of the sterile stalk. 



14. Dendronephthya longicaiilis (Kiik.). 



Described by Kiikenthal in ' Versuch einer Revision der 

 Alcyonarien,' ii. pp. 633-634 (1905). 



Diagnosis: — Umbellate; very long stalked ; somewhat flattened 

 polyparinm ; basal branches foliaceous and form a collar ; polyps 

 in small, loose umbellate groups ; polyp stalks usually short, but 

 may reach 2 mm. long; supporting bundle weak; point spicules 

 one pair only, one of which is stronger; crown of 4-6 ; grade YI.; 

 spicules : cortex of the branches covered with stout spindles 

 bluntly tuberculate, cortex of the stalk with many stellate forms ; 

 colour : general cortex has the surface pink- white, pol}p-stalks 

 red-brown, anthocodial spicules almost translucent. 



Anthocodial Grade and Formula : — 



YI. = I -h 1 P -F 4-6 Cr + weak S.B. 

 Descriptive Notes : — 



1. Colony as a lohole. A single, peculiar specimen unlike any 

 other in the collection ; marked by a long flexible stalk (10 cm. 

 out of a total of 13) ; of uniform diameter (1-3 cm.) ; and bearing 

 a rather loose umbellate polyparinm, somewhat flattened. 



2. Branching. The basal branches of the polypai-ium ai^e 

 foliaceous and form a collar turned downwai-ds. There are but 

 few branches extending transversely, so that the top of the 

 polyparinm appears rather truncate. 



3. Colouring. General surface of the cortex is pinkish white, 

 the polyp stalks reddish brown, while the anthocodial spicules 

 are almost translucent. 



4. Polyp stalks are on an average about 1 mm. long, but a 

 length of 2 mm. maybe attained. They appear to be bare on 

 the ventral side. 



5. Polyps. The bundles of polyps are disposed in small loose
