I have named this species in remembrance of Mr. Roland 

 Trimen, F.R.S., who was for many years the leader of South 

 African Zoologists. 



It will be observed that the pores on tlie arms present very 

 much the same characters as in Ophiozona capansis. 



4. Amphiiira incana. 

 Ampliiiira incana, Lyman, Bull. Mus. C Z. v. (1878), 



This species was obtained off the South Head, Tugela River, 

 N. by W., 4^ miles. Depth, 25 fathoms, black mud. Refer. 

 No. 11480A. 1 am not very confident of the accuracy of this 

 determination. 



Other species of the genus were collected off Lion's 

 Head, S.E. \ S., 10^ miles. Depth, 69 fathoms. Bottom, 

 red and green sand. Refer. No. 2038. But the specimens were 

 not in good condition, and T cannot assign them to any known 

 species. 



5. Ophiothamnus remotus. 



Ophiothmmtus remotus. Toyman, Chall. Rep., p. 212. 



The " type " of this species was a single specimen taken off 

 the Agulhas Bank ; it is well, therefore, that a good set was ob- 

 tauied from Cape Natal, N.W. \ W., 5^ mi., Refer. No. 18/ A, and 

 a few from off Algoa Bay, close to Riy Bank, Refer. No. 97.

Ophiotlirjx rosco-cocnilans, Grube, JB. Schles. Gesell. (1868),

This species (from St. Helena) was so briefly described that 

 one cannot be certain of recognising it. 



Obtained on Rocky Bank. False Ba}-. Depth, 17-27 fathoms. 

 Bottom, rocks. Refer. No. 15612.
