Off Mt. Lihau, West Maui, 25-75 feet., D. Tliaanum. Also off 

 Honolulu, 35-50 feet., D. B. Langford. 



This species differs from T. nihda by the absence of a raised 

 ■inner lip, though it is often somewhat calloused. It is much like 

 T. swainsoni, as I have identified that species, but lacks the inter- 

 stitial sculpture and the raised inner lip of that species. Seventeen 

 specimens in coll. A. N. S. P. and M, C. Z. 



It appears to be what Pease identified as T. swainsoni Desh., but 

 that is described as having the early whorls transversely striate. 



It is named for Mr. Wm. F. Clapp, who has kindly assisted in the 

 examination of Pease's species. 



Terebra lanceata oahuensis n. siibsp. PI. XII, fig. 7. 



The shell is rather smaller than lanceata and for at least half of 

 its length the ribs extend entirely across the whorls ; on the later 

 whorls they shorten, but are visible below the suture on the last. 

 The pattern of brown lines, interrupted or bent at the periphery, 

 is similar to that of lanceata. 



Length 38, diameter 6.4 mm. 



Off Honolulu, 6 to 8 fathoms. D. B. Langford. 



Dr. Dall (Bull. M. C. Z., 43, p. 249), has formed a subgenus Acu- 

 mima for Terebra lanceata (Linne); but that species is conchologi- 

 cally close to T. strigilata of Born and Lamarck, and would seem to 

 belong to Hastula. 



Terebra verreauxi Desh. 



Journ. de Concliyl., II, 1857, p. 95, pi. 5, fig. 3. 



Exactly what species was intended by B'uccinmn stricjikdum 

 Linne (Syst. Nat. X, p. 741; Hanley, Ipsa Linn. Conch, p. 261) is 

 not known. As Hanley remarked, the identification of Born has 

 been generally accepted.* He states that the shell in Linne's cab- 

 inet is T. concinna Desh. 



For the Hawaiian form we prefer to use the name given by Des- 

 hayes, whose description and figure represent this form. It is one 

 of the most beautiful of the genus. The color is from deep olive 

 to ecru-olive or more ochraceous, with white bands at sutm-c and 

 below periphery, the former decorated with regular black-brown 

 spots. It has been taken off Honolulu, 6-8 fms (D. B. Langford), 

 and at Haena, Kauai (Bryan).
