AET. 18 SMALL SHELLS DEEDGED BY '' ALBATROSS '^ BALL 81 



Cat. No. 360173, U.S.N.M., contains 14 additional specimens from 

 the type locality. 



TURBONILLA (STRIOTURBONILLA) MYIA, new species 



ShelUarge, elongate conic. Nuclear whorls and early postnuclear 

 whorls decollated. The sLx and a half remaining are well rounded, 

 almost appressed at the summit, crossed by strong, almost vertical 

 axial ribs of which 14 occur upon the first and 16 upon the remain- 

 ing turns. These ribs become slightly enfeebled and expanded toward 

 the summit. Intercostal spaces about as wide as the ribs, strongly 

 impressed. Suture moderately constricted. Periphery of the last 

 whorl strongly rounded. Base short, strongly rounded. Entire sur- 

 face of spire and base marked by rather strong lines of growth and 

 numerous moderately strong spiral striations. Aperture subquad- 

 rate; posterior angle obtuse; outer lip fractured; inner lip almost 

 straight, stout, reflected over and appressed to the base for about 

 half its length, provided with an obsolete fold a little anterior to its 

 insertion. 



The type, Cat. No. 347844, U.S.N.M., comes from United States 

 Bureau of Fisheries Station 2415, in 440 fathoms, sandy bottom, 45.6° 

 bottom temperature, off Georgia. It consists of the last 6.5 whorls 

 which measure: Length, 7.9 mm.; diameter, 2.3 mm. 



Cat. No. 108287, U.S.N.M., contains another specimen from the 

 same locality. 



TURBONILLA (STRIOTURBONILLA) ENNA, new species 



Shell slender, elongate-conic, bluish white, semitranslucent. Nu- 

 clear whorls forming a rather large, depressed helicoid spire, which 

 has two and a half whorls. Postnuclear whorls well rounded, rather 

 high between summit and suture, marked by moderately strong, 

 almost vertical axial ribs, of which 16 occur upon all but the last two 

 turns, which have 18. Intercostal spaces about as wide as the ribs. 

 Suture rather strongly constricted. Periphery of the last whorl well 

 rounded. Base moderately long, well rounded, smooth excepting the 

 incremental lines and fine, closely spaced spiral striations, which are 

 characteristic of both base and spire. Aperture elongate oval; poste- 

 rior angle obtuse; outer lip thin; inner lip almost straight, reflected 

 over and appressed to the base for about half its length, provided 

 with an obsolete fold a little anterior to its insertion. 



The type, Cat. No 360175, U.S.N.M., comes from United States 

 Bureau of Fisheries Station 2668, in 294 fathoms, sandy bottom, 

 46.3° bottom temperature, off Fernandina, Fla. It has 8.5 postnu- 

 clear whorls, having lost the tip and probably a fraction of the first 

 postnuclear turn, and measures : Length, 4.2 mm. ; diameter, 0.9 mm.
