In colour very similar to 7. amewna, Deshayes, 7. Andamanica, Melvill 
and Sykes, and 7. Gotoensis, Smith, but differing from the first two in 
its flatter and shorter whorls and closer and more delicate riblets, and 
from the last by different spiral sculpture. Named after Miss Lois 
Trotter, of Durban.

Terebra casta, Hinds: Sowerby, Mar. Shells 8. Afr., Appendix, p. 13. 
Hab.—Umkomaas, Natal. 
The specimens from Natal differ from the typical form both in 
colour and sculpture. They are more copiously stained with reddish 
brown, and the riblets are more acute, not flattened. 7. bdbipartita, 
Deshayes, from the Sandwich Islands, which I regard as a variety 
of this species, has similar sharpish coste, but is somewhat differently 
coloured.
