HYDUOCORALLIXE GEXUS ERRIXA. 883 



Errina (Labiopora) NOV.E ZELANDi^. (Facies Benhami.) 

 (PI. XCIV. figs. 1 & 2 ; PI. XCVI. fig. 13.) 



This specimen was also fovinrl in Preservation Inlet and lent to 

 Prof. Benbam by the Colonial Mnseiim. One branch of this 

 specimen was well preserved in spirit. The colony is flabelliform, 

 with profuse ramification and abundant anastomoses. The 

 terminal branches are thick, the diameter of such a branch at a 

 distance of 3 mm, from the extremity being about 3 mm. All 

 the branches are approximately circular in section. 



Colour : salmon-pink. 



Surface minutely granular and substance minutely reticulate. 



Grooved spines numerous, arranged roughly in rows. These 

 spines are more numerous and longer than in the facies "Bamosa." 

 They are, moreover, frequently arranged in clusteis, so that they 

 have the appearance of "branched spines" (fig. 13). The 

 grooves are in general turned away from the apex, but when 

 the projections are clustered they turn in all directions. 



Gasteropores equally numerous on the two sides of the flabellum. 

 "Without a lip. Diameter varying considerably from 0"13 mm. 

 to 0*17 mm. 



Large dactylopores 0-06 x 0'16 mm. 



Small dactylopores not infrequent, 0*05 mm. in diameter, 



Errina (Labiopora) nov^ zelandi^. (Facies Dendyi,) 

 (PI. XCIY. fig. 4.) 



This specimen was obtained in Milfoi-d Sound, W. coast of 

 South Island, and was lent to me by Professor Dendy. 



It is not very profusely branched, but probably has a flabelli- 

 form mode of gi-owth. The terminal bi-anches are delicate and 

 of approximately the same diameter as. those of facies " Bamosa." 

 There are no anastomoses in the specimen. 



Colour : salmon-pink. 



The surface is minutely granular and the substance minutely 

 reticular. 



Grooved spines not very crowded but quite irregularly disposed, 

 not in rows, never in clusters. The groove in all cases turned 

 away from the apex of the branches. 



Gasteropores on both sides of the branches but rather more 

 numerous on one side than the other. Usually guarded by a 

 small lip. Diameter 0*22 mm. 



Large dactylopores 0'06 x 0-11 mm. 



Small dactylopores 0*05 mm. in diameter, usually guarded by a 

 shallow collar or lip. 



A feature of this specimen that should be mentioned is the 

 suppi-ession of the spines on the larger branches. Only the 

 terminal branches are echinate.
