some of the CHALLENGER specimens and have no doubt of their 

 identity. They come from eight stations and as there are 77 of 

 them, the species is evidently common in suitable localities. The 

 disk-diameter ranges from '2 to 7'5 mm. The growth changes are 

 very trivial: in the smallest specimen there are only 5 arm-spines, 

 even at base of arm, and they are pointed, the radial shields are 

 relatively larger, the disk scales are fewer and the arm-plates are 

 relatively longer than in the adult.

AMPHIPHOLIS MINOR. 



Ophiactis minor Doderlein, 1910. Schultze's Zool. Anth. Ergeb. vol. 4, 



Ifg. 1, p. 253; pi. V, figs. 3, 3a. 

 Amphipholis minor H. L. Clark, 1915. Mem. M. C. Z., vol. 25, p. 243. 



It is very curious that Doderlein did not recognize this species as 

 an Amphipholis when it is so similar to the cosmopolitan A. squa- 

 mata, with which he is unquestionably familiar. There is a single 

 specimen (3'5 mm. across disk), of this species, in the PIETER FAURE 

 collection. It agrees well with Doderlein's description but differs 

 from the figures in having an elevated disk and sharper arm-spines. 

 The species was previously known only from Angra Pequena Bay 

 where it occurs with Amphiura capensis. 



P.F. 13732. Great Fish Point, N. by W., 7 miles, 49 fms. S. 

 and sh. 1 specimen; adult.
