WITHIN THE GKNUS DENDRONEPUTll YA. 55 



shows 4-5 horizontal spindles closely packed in a crown and of a 



pair of converging spindles in each of the 8 points, one member 



of the pair often larger than the other 



and projecting a little beyond the polyp. Text-fig. 14. 



The supporting bundle is very strong, 



and in it one spindle may attain a length 



of 3 mm. 



7. Other spicules. The surface of the 

 stalk is densely covered with roughly 

 tuberculate multiradiate discs, often 

 with a central knob, which fit into each 

 other. 



Deduction : — This specimen does not 

 agree with previous descriptions in 

 colouring or in showing foliaceous basal 

 branches, yet I think it should be 

 ranked within the heading of B. cervi- 



). cervicornis Wr. & Stud. 



Localities : — Stations 305, 310. 



8. Dendronephtliya mirahilis (Henderson). 



Described by Henderson in ' Alcyonarians of the Indian 

 Ocean,' Part II. pp. 49-51 (1909). 



Diagnosis : — Divaricate ; loose ; contour irregular ; distinctly 

 flattened ; polyps in small bundles of about 6 ; polyp stalks 

 medium ; supporting bundle medium ; point spicules 5 pairs, 

 with the uppermost pair slightly projecting; crown absent; 

 gi-ade lY. ; spicules : many of the stalk spicules chai-acteristic 

 in appearance because of the length and strength of the pro- 

 tuberances ; colour : colony as a whole white, polyp stalks, 

 point spicules, and supporting bundle amber-yellow. 



Anthocodial Grade and Formula : — 

 lY. = 5p + Or + medium S.B. 

 Descriptive Notes : — 



1. Colony as a tvhole. A white, divaricate colony. 



2. Branching. Loose, divaricate, with irregular contour and 

 very distinct flattening. It should therefore be referred to 

 Klikenthal's group Divaricatas, subgroup cervicornis. Yet^ it 

 agrees in several respects with Henderson's D. mirabilis, which 

 he places in the rigicla group. 



3. Colouring. Polyp stalks, spicules of the anthocodial arma- 

 ture and of the supporting bundle amber-yellow. 



4. Polyi) stalks not more than 1 mm. long. 



5. Polyps occur in small bundles of about 6 in number. 



6. Polyp spicules. The anthocodial armature consists of 

 8 double rows of about 5 pairs, converging steeply, and with the 

 uppermost pair slightly projecting. This does not agree well
