60 DK. W. RAE SHERRIFPS ON EVOLUTlOX 



a long, limp stalk; total length 5 cm., of which 1-5 is poly- 

 parium. 



2. Branching. The lowest branches show only hints of being 

 foliaceou^. 



3. Oolou7\ A fine coral-red in stalk, Text-fig. 18. 

 supporting bundle, polyp stalk, and ten- 

 tacles ; the general cortex of the poly- 

 parium is white flushed with red, and 

 the anthocodial spicules are white. 



4. Polyp stalks long. 



5. Polyps in divergent groups of 4-10. 



6. Polyp spicules. The armature of 

 the anthocodise consists of 8 pomts of 

 small spicules, very compactly disposed, 

 6-8 en chevron in each point ; the upper- 

 most pair in each row predominate and 

 may project slightly. 



Tlie supporting bundle is strongly B. microspiculata Piitter 

 developed, and one strong central 



spindle projects for 1 mm. ; the spicules here are thickly but 

 finely spinose. 



7. Other spicules. The tentacles show a double dorsal row of 

 transversely disposed, narrow, jagged, reddish spicules ; the cortex 

 of the sterile stalk has thick spindles, usually bent, covered with 

 large warts, often compound. Along with these are smaller bent 

 spindles, often with large prongs on the convex side. There ai'e 

 also numerous bright I'ed iri-egularly quadrangular or knob-like 

 corpuscles, which may be vaguely called '' stars." These are 

 well figured by Piitter. All these stalk spicules with prongs are 

 suited for interlocking. 



Perhaps the most characteristic features are (1) the numerous 

 compact chevron pairs of the anthocodial points, and (2) the 

 quadrangular " stars." 



Locality : — Station 315. 



12. Dendronephthya orientalis (Hend.). 



Described by Henderson in ' Alcyonarians of the Indian 

 Ocean,' Part II. pp. 30-32 (1909). 



Diagnosis: — Divaricate; no regular outline; somewhat flat- 

 tened ; polyps in loose clusters ; polyp stalks long ; supporting 

 bundle strong ; point spicules 1 pair only, of which one member 

 is the larger and markedly projects ; crown of 3 loose horizontal 

 rows : grade VI. ; spicules : tentacles conspicuously armoured, 

 in the cortex very conspicuous strong spindles and numerous 

 small warty triradiates and multiradiates ; colou]" : general surface 

 wliite, anthocodial and supporting-bundle spicules pink. 



Anthocodial Grade and Formula : — 



YI. = 1 P -t- 3 Or + strong S.B.
