clearness, to ignore their definitions in the two cases, and to name 

 it S. globator Bell. The species from the Korean Straits described 

 by Mr. Sladen as S. sulcatum seems to me to be referable to this 

 form. Owing to the uncertainty of identification of species of 

 this genus, I have omitted their recorded distribution, but it is un- 

 doubtedly extensive. 



The colour of the spines in the specimens collected was whitish 

 yellow, with irregularly spaced, narrow, transverse purple bands ; 

 iu one specimen the abactinal spines were all devoid of any purple 

 pigment.

Locality. Singapore ; two specimens dredged in 10 fathoms on 

 sand. The species does not appear to be very common at Singapore, 

 although M. de Loriol mentions having examined several speci- 

 mens from that locality. 



The description given by Mr. Teuison- Woods of individuals 

 from N.E. Australia accords exactly with those iu the present 

 collection ; and I think there can be very little doubt that they are 

 the same species as Alexander Agassiz's S. rarispina ; the pale 

 wedge-shaped sutural markings so characteristic of this species 

 are very obvious iu both specimens. So far as I can judge, this, as 

 suggested by Loven, is the Echinus sphceroides of Linnaeus, but I 

 cannot a°ree with him in identifying it with S. globator (/3) 

 described by Prof. Bell (P. Z. S. 1880).
