ALCYONARIA WHITELEGGE. 215 



SARCOPHYTUM TROCHELIOPHORUM, var. AMBOINENSE, Marenz. 



Sarcophytum trocheliophorum, var. amboinense, Marenz., Zool. 

 Jahrb., Bd. i., 1886, p. 361, pi. ix., tig. 6 ; Wright & Studer, 

 Chall. Rep., Zool., xxxi., p. 249, pi. xli., fig. 11. 



One small specimen, the polyps are quite retracted, the sipho- 

 nozooids are distinct and disposed in circles. The short thick 

 spicules are characteristic of this form. (See fig. 6c on Maren- 

 zeller's plate.) 



SARCOPHYTUM LATUH, Dana. 

 (Plate x., figs, la-/.) 



Alcyonium latum, Dana, Zooph. U.S. Explor. Exped., pi. Iviii., 

 figs. 6, a, b, b; Synop. Rep. Zooph., 1859, p. 125. 



The single example obtained, differs slightly from the type as 

 figured by Dana ; it is smaller, more depressed, and the lobes are 

 fewer. 



The sterile column is well developed, it is 55 mm. high at its 

 highest point, and 30 mm. at its lowest ; the surface is longitu- 

 dinally sulcate and very harsh to the touch. 



The capitular margin is a little swollen, but not at all re volute, 

 the upper surface generally presents a minutely beaded appear- 

 ance, due to the elevation of the walls surrounding the orifices of 

 the polyps. 



The autozooids, which are 1 mm. apart, are encircled by six or 

 seven siphonozooids, the latter being also common to the encircling 

 series of adjoining autozooids, as shown in Dana's fig. 6a. 



The ccenenchyrna spicules are abundant, and consist of fusi- 

 form, and of subcylindrical spindles, studded with whorled, 

 granular, or spiny tubercles. Size -3 by -08, '4 by !, -3 by '15, 

 35 by -15 mm. In addition to these, there are a few crosses and 

 comparatively smooth spiny spindles. 



The spicules of the cortex are tuberculated clubs, which form a 

 very dense crust, they are variable at the blunt end, some are 

 broad and others obliquely pointed. Size -12 by -03, -2 by -04mm. 



The specimen has the same general shape as that figured by 

 Dana, consisting of two subfoliate expansions ; there is evidently 

 an error in fig. 7, the right half having the sterile column coloured 

 and dotted to represent polyps similar to those on the capitular 

 surface. 



The spirit specimen is dark stone colour.
