Linck's figure gives a very good idea of a typical specimen of 

 this species, which is common at Zanzibar and has been reported 

 from Mozambique by both Peters and Bell.

This is a very variable species and the growth changes and 

 limits of variation need very much- to be worked out. In some spe- 

 cimens, spines and even the big tubercles are nearly or quite 

 lacking while at the other extreme, every big dorsal or super- 

 omarginal plate carries a small or moderate spine. Peters re- 

 ported the species from Mozambique and it is not recorded from 

 south of there, but in the present collection is a specimen from 

 Mossel Bay, Cape Colony, which thus extends the known range of 

 the species many hundreds of miles to the south. The specimen is 

 a small one (R 60 mm.) and lacks one ray, which is however 

 beginning to regenerate. There are no spines anywhere but many 

 of the marginals, especially of the lower series, and a number of 

 abactinal plates bear more or less elevated tubercles. The dry spe- 

 cimen is light yellowish-brown. Mossel Bay. C. W. Black. 1914.

This widely distributed Indo-Pacific species is very variable and 

 has been described under a number of names. It has been reported 

 from Mozambique and there is a young individual from that place
