312 FUNAFUTI ATOLL. 



In addition to the above, two crosses have been observed, one 

 equal rayed and similar to the larger spicules, the other resembling 

 the smaller polyp spicules. 



(1.) The external spicules of the verrucas are similar to but 

 smaller than those of the stem. Size 1- by -15, 1-5 by -2, 2' by 

 2 mm. 



(2.) Smaller deep-seated fusiform spicules, with distant tubercles 

 or low spines, rather numerous in the verrucse, particularly at 

 the base. Size -5 by -08, -8 by -1, 1- by -15 mm. 



(3.) Curved collar spicules, with the ends smooth and rounded, 

 the central region with a few distant blunt spines or low tubercles. 

 Size '7 by !, - 8 by '12 mm. 



(4.) The spicules of the operculum consist of a larger external, 

 and of a smaller internal series, the larger are tuberculate, fusiform 

 or subclavate with the free ends acute and the fixed ends blunt. 

 They measure -6 by -08, -7 by -09, and -8 by -1 mm. ; the smaller 

 are slightly curved fusiform or subclavate, with either acute or 

 blunt ends and a few distant tubercles. Size '25 by "05, 4' by 

 08 mm. 



(5.) The tentacle spicules are very numerous, and consist of 

 straight, curved, or bent rods, with faint indications of spines, 

 they are imbedded in the tissues and may be traced below the 

 collar, probably in the apices of the inverted tentacles. 



All the spicules except the last-named, which are colourless, 

 are of a dark brick-red by transmitted light. 



There are no traces of spicules of the form called "stachel- 

 platten " by Kolliker. 



The colour in formol is purplish-red. 



This species differs from A. chcenielon and A. argentea by the 

 larger size of the polyps arid spicules. 



VlLLOGORGIA FLAGELLATA, sp. nOV. 



(Plate xvi., tigs. 16-20.) 



There are seven fragments all more or less denuded owing to 

 their being entangled in the tow, one is attached to the dead stem 

 of a species of Verrucella. 



The largest specimen is 95 mm. in height and from 15 to 20 mm. 

 in width, it is flattened in a plane opposite to that of the branching, 

 the stem is '7 ram. in diameter, the branches are lateral, opposite 

 or alternate, simple or bearing long slender thread-like twigs. 

 The axis is horny, yellowish, the branches and twigs are flexible 

 the base of the stem rather brittle. When viewed by transmitted
