102 ZOOLOGICAL COLLECTIONS MADE DURING [Jan. 4, 



and two of small ones, which are exterior; all are entirely retracted. 

 The sides of the body are almost hid by the disk in its present state : 

 they are about 5 miilims. high; the base is 11, and the disk 13 

 broad. The only unevenness of the body-surface is an occasional 

 indication of the mesenteries. 



Hub. Same as preceding. 



It is obviously impossible to identify these specimens satisfactorily 

 by the few characters left to them. 



Two other Actinians are represented, each by a minute specimen 

 from Coquimbo Bay, Chili. One is almost entirely black in spirit, 

 the other nearly white, apparently with black-tipped tentacles. They 

 answer to none of the species enumerated in Gay's ' Chili ' with any 

 certainty ; possibly the light-coloured species may be Actinia nivea 

 of Lesson (Voy. de Coquille, Zooph. p. 80, pi. iii. fig. 8). The 

 depth is 4-8 fathoms. 



AXOHELIA BRUEGGEMANNI, Sp. U. (Plate VI. fig. 7.) 



Corallum subcylindrical, branching. Ccenenchyma compact ; sur- 

 face covered with minute pointed tubercles at some distance apart, 

 and marked by very slight and irregularly developed longitudinal 

 ridges. Calicles round or slightly oval, the long axis following that 

 of the corallum itself; maximum diameter 1 miliim., generally more 

 or less raised above surface. Septa 8 in number, in one cycle, equal 

 in size, commencing outside the calicle as ridges, and projecting 

 above its edge as prominent square-topped teeth ; at a distance 

 inwards varying from one fourth to half the radius they fall away 

 perpendicularly and join the columella ; a second cycle is indicated 

 by a slight swelling in the calicular rim between each of the two 

 primaries. Columella mound-like, culminating in a short, sharp 

 median point. Interseptal spaces deep. Colour of corallum white. 



Hab. Victoria Bank', off S.E. Brazil, 33 fathoms; also (spe- 

 cimen already in British Museum) West Indies. 



Obs. The specimen from the West Indies already in the Museum, 

 but not described, has the form of (apparently) two stems which 

 have fused laterally at one point. It bears several short tubercular 

 processes, and is forked at the upper end ; it measures £0 miilims. 

 in length by 10 in maximum thickness. The calicles differ from 

 those of the Brazilian specimen in being always round, in being 

 little, if at all, salient, and in the superior radial length of the 

 septa ; it also differs immensely from it in relative stoutness, as the 

 other measures only 1.5 miilims. in length by 2 in thickness. In 

 both cases the stem has a somewhat oval section; the calicles are 

 between 1 and 2 miilims. apart. The West-Indian specimen was 

 probably a dead one and somewhat overgrown ; so it is fortunate 

 that one evidently taken alive has been secured. The differences 

 between the two are important, especially the shape of the calicles, 

 but apparently not sufficient to justify their separation. This species 

 is named after the lamented author who was the first to recognize
