the spots yellow-brown. It has l)een merged with this species by 

 Tryon. Type 37 mm., but the Aden example is only 30 mm. in 

 length. T. bimida Desh., also from Japan, seems exceedingly close, 

 and we should conjecture from the plate in Reeve, Conch. Icon., 

 fig. 117, it might be identical. 



14. — Terebra helichrysum Melv. and Stand. 



T. helichrysum Melv. and Stand., Ann. and Mag. N.H., 1903, 

 ser. vii., vol. xii., p. 310, pi. xxii., fig. 14. 



Hab. : P.G., Mussandam, 47 to 55 fathoms. Muscat, 30 fathoms. 



A handsome species, allied closely to the last {^otoe?isis) and to 

 alveolata Hinds. From this it differs in the character of the longitu- 

 dinal riblets, which are fewer in number in helichrysum, so that the 

 interstitial spaces are broader than long, the same pitting being 

 observable that there is in both the other species. The colour is a 

 brighter stramineous, or rather, ochreous, than obtains in its con- 

 geners, and it seems a handsome addition to the genus. Our largest 

 specimen measures 25 mm. T. marmorata Desh., a North Australian 

 species, seems also comparable. 



15. — Terebra lepida Hinds.

Tryon merges this with T. strigilata (L.), and it must be confessed 

 much similarity exists ; the smoothness and impressed character of 

 the ribs are identical. T. strigilata also occurs in the Persian Gult 

 region not uncommonly.

Described originally from specimens in the British Museum, dredged 

 many years ago by Col. (afterwards Sir) Lewis Pelly, K.C.B., and 

 presented by Mr. Macandrew. This is one of the most engaging 

 little species possible. At the request of Mr. Smith we figured it in 

 our paper, reference to which is given above. It is somewhat broad, 

 slightly swollen below the sutures, spiral sulcus well defined, many
