50 DR. W. RAE SflBRRIFFS ON EVOLUTION 



consisting of two strong, very thorny, convei"ging spicules bent at 



the base in hockey-club-like fashion, one slightly larger than the 



other. Between adjacent points lie a 



pair of much smaller, straight spindles Text-fig. 10. 



longitudinally disposed, but in some 



cases there seem to be two pairs (thus 



connecting with D. dcederleini). Below 



the points there is a crown of horizontal 



spindles in two or three rows, rather 



irregularly disposed. 



The supporting bundle is strongly 

 developed, especially as regards the three 

 uppermost spindles, the lower median 

 one of which projects for almost X). jjimicea Stud. 



1 mm. 



Deduction: — A.mong the membei-s of the hemprichi group 

 there are several with only one pair of spicules in each of the 

 anthocodial points, and beside these this specimen must be 

 ranked. 



It agrees very closely with D. punicea in the following 

 features : — 



(1) each anthocodial point composed of two spicules, one 



slightly larger than the other ; 



(2) between adjacent points usually a single pair of small 



intermediate spicules ; 



(3) below the points the crown of hox^izontal spindles is present 



with two or three rows ; 



(4) the strong supporting bundle.

4. Dendronephthya ehrenbergi (Kiik.). 



Desci-ibed by Kiikenthal, ' Korallentiere des Rothen Meei^es,' 

 p. 56 (1904). 



Diagnosis : — Divaricate ; contours irregular ; polyps in little 

 groups of 5-8 ; polyp stalks short ; supporting bundle medium ; 

 point spicules 6 pairs; crown absent; grade III.; spicules: canal- 

 walls show few bent rough spindles, the stalk cortex has very 

 distinctive long curved red spindles and irregular clubs, discs, and 

 spheres ; colour : rich red in the coenenchyma, anthocodial spicules 

 grey-yellow, polyp spicules of the points white. 



Anthocodial Grade and Formula : — 

 II. = 6 p -I- Cr 4- medium S.B. 



Descriptive Notes : — 



1. Colony as a ivhole. Ten specimens in all, including two 

 fine specimens agreeing closely with Kiikenthal's definition of 

 this species, the largest 40 cm. in length.
