ALCYONARIA WHITELEGGB. 217 



The autozooids are very irregularly disposed ; they are few in 

 number, and on the central regions of the lobes separated from 

 each other by wide intervals. On the margins and summits of 

 the lobes they are closer, and about 1 to 2 mm. or even less apart. 



The siphonozooids are numerous, distinct, and plainly visible 

 to the unassisted eye ; between the widely separated autozooids 

 there are as many as twelve, whilst on the margins, where the 

 autozooids are crowded, they are fewer and disposed in circles. 



The spicules of the ccenenchyrna consist of 



(1.) Straight rather acute ended spindles, the smaller of which 

 are often unequal and subclavate. The tubercles are in whorls 

 and somewhat minutely spinose. Size -15 by -03, -3 by -09 mm. 



(2.) Short, stout, subcylindrical, with from four to six whorls 

 of spiny tubercles. Size '15 by -07, '2 by 1 mm. 



In addition to the foregoing there are numerous spiny spindles 

 and some crosses. The spicules of the cortex are rather narrow 

 tuberculated clubs. Size -12 by -02, -15 by -05mm. 



The colour in spirits is umber.

LOBOPHYTUM MAEENZELLERI, Wright <k Studer. 



Lobophytum marenzelleri, Wright & Studer, Chall. Rep., Zool. 

 xxxi., p. 251, pi. xlii., fig. 1. 



One specimen of an oval shape, 80mm. long and 40 mm. wide. 

 Only a small portion of the sterile column remains, it is 30mm. 

 high. The lobation of the capitulum, autozooids, siphonozooids 

 and spicules, agree with the published description. 



The specimen is of a yellowish-white colour. 



LOBOPHYTUM TUBERCULOSUM, Quoy & Gaim. 

 (Plate xi., figs. 3o-/.) 



Lobophytum tuberculosum, Quoy & Gaiin., Voy. Astrolabe, Zooph., 

 iv., p. 274, pi. xxiii., figs. 4-5. 



In a small example referred to this species the sterile stem is 

 mostly torn away, the remaining portion is 15 mm. high and 

 25 mm. wide. 



The capitulum is 80 mm. long, 60 mm. wide, and 20 mm. high. 



There are seven primary lobes arising from the expanded base, 

 each bearing from five to twenty secondary round, oblong, or 

 subreniform lobes, their height seldom exceeding their lesser 

 diameter. 



The autozooids are crowded, with the margins of the orifices 

 deeply sunk, they are from -5 to 1 mm. apart.
