cords. Aperture small, the anterior canal recurved. The colu- 

 mella is biplicate within. 



Length 30, diameter, 6.7, aperture 6 mm.; 17 whorls. 



Off Waikiki, Oahu, in 25 to 50 fms. D. B. Langford. 



In form and color somewhat like T. decorata Desh. (Proc. Zool. 

 Soc. 1859, p. 314, no. 214), which is said by Reeve to be identical 

 with T. tessellaia Gray (P. Z. S. 1834, p. 61) ; but that species is en- 

 tirely distinct in sculpture. 



Terebra flavofasciata n. sp. PI. Xll, fig. 3. 



Shell shaped like T. prophiqua Pse.; white, part of the intercostal 

 spaces of the presutural band marked with vinaceous russet; 3 

 ochraceous-buff bands, one below the sutural band, another narrow, 

 at the periphery, and the third occupying the base. Sculpture of 

 smooth, rounded axial ribs, slightly wider than their intervals, 19 

 on the last whorl of the type, 25 mm. long, (16 in a shell 17 mm. 

 long). The intercostal intervals have many spiral cords wider 

 than their interstices, 10 on the penult whorl, below a series of 

 deeper transverse pits defining the presutural band. Upon the 

 band the interstitial spirals are finer. On the base the ribs become 

 obsolete and there are coarser spiral cords. Aperture rhombic, 

 somewhat channelled and yellow at the base. 



Length 25, diameter 5.5, aperture 5.3 mm.; 15 whorls. 



Off Launiupoko camp. West Maui; sma'l specimens, 17-18 mm. 

 long, off Honolulu, 6 to 8 fms. D. Thaanum and D. B. Langford. 



Smaller than T. propinqua and T. pertura, with more numerous 

 spirals and different coloration. Possibly to be compared with T. 

 sulcata Pease (Amer. Journ. Conch., V, 67), the type of which is lost. 



Terebra clappi n. sp. • 



The shell is slender, shaped about as in T. nitida, glossy, dark 

 vinaceous brown, the ribs and an ill-defined belt below the suture 

 paler or whitish. Whorls nearly flat, with well-impressed suture, 

 the last whorl contracting downward. Sculpture of straight, angu- 

 lar ribs, rather suddenly terminating at the base, the intervals hav- 

 ing a spiral series of impressions defining an infrasutural band; 

 these impressions sometimes nicking the summits of the ribs sHghtly. 

 In the type there are 15 ribs on the last whorl. The aperture is a 

 little dilated below. Columella one-folded. 



Length 17.5, diameter 3.8, aperture 4.2 mm. 11 post-embryonic 

 whorls. 



Length, 21, diameter 4.5 mm., 13 post-embryonic whorls. Hono- 

 lulu, Pease Coll., M. C. Z., 49964.
