Show 1900.] MR. F. P. BKDFORD ON MALAYAN ECHliVODERMS. 283 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. sulcatus seems to m e to be referable to Ibis form. Owiug to the uncertainty of identification of species of this genus, I have omitted their recorded distribution, but it is undoubtedly 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.

Salmacis rarispina, Alexander Agassiz, Revision of Echini, pt. 3, 1872, p. 475. References. J. E. Tenison-Woods, Proc. Linn. Soc. N . S. W . vol. iv. 1878, p. 161. P. de Loriol, Rev. Suisse de Zool. t. i. 1893, p. 370. 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 exatniued several specimens from that locality. The description given by Mr. Tenison-Woods of individuals from N.E. Australia accords exactly with those in the present collection ; aud 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 lean judge, this, as suggested by Loven, is the Echinus sphceroides of Linnaeus, but I cannot agree with him in identifying it with S. (globator (ft) described by Prof. Bell (P. Z. S. 1880). 1.. 2. . Diam. Height. . 3 9 24 . . 54-5 38 Measurements. Calyx. Peristome. 7-0 11 14-5 Percentage values: H. C. 61-5 17-9 68-8 D = 100, P. 28-3 26-6 i). L A G A N U M DEPRESSUM de Blainv.
