9. Oliva {Olivella) ephamitta, 1 Watson (PL XIII. fig. 10). 



Oliva (Olivdla) ephaviilla, Watson, Prelim. Report, pt. 12, Journ. Linn. Soc. Lond., vol. xvi. 



p. 342. 



Station 122. September 10, 1873. Lat. 9° 5' S., long. 34° 50' W. Off Pernambuco. 

 350 fathoms. Eed mud. 



Shell. — Very small, oblong, glossy, white, with a high blunt spire, a conical base, and 

 a long narrow mouth. Sculpture : Longitudinals — the lines of growth are barely 

 recognisable. Spirals — there is scarcely a faint appearance of these. Colour probably 

 porcellanous white in the living specimen. Spire high, convexly conical, minutely 

 scalar from a very small projection below the suture. Apex bluntly rounded. Whorls 

 4|, with a minute projection below the suture, very slightly convex at the sides. Suture 

 minutely perpendicularly 2 channelled. Mouth oblong, small, pointed, and deeply chan- 

 nelled above, slightly narrowed below. Outer lip sharp, prominent, regularly arched 

 from the body to the point of the pillar, not being in the slightest degree emarginate in 

 front. Inner lip : there is a thick, irregular-edged pad, which in front scarcely coils 

 round the front of the bent, twisted, short, truncated, and toothless pillar. H. O'lG in. 

 B. 0-07. Penultimate whorl, height 004. Mouth, height 0-09, breadth 0*03. 



The name of this little species is meant to signalise its remarkable resemblance to some of the 

 minute Achatinas, such as Cionclla acicula, Mull., or something between that and Lovca leacociana, 

 Lowe. Thinking, from the figure, that it approached Oliva tchuekhana, d'Orb., I asked Mr B. A. 

 Smith to compare it with the type of that species preserved in the British Museum. He replies : " I 

 am sure that your shell is not Oliva tehudchana, d'Orb. This lias the whorls flat at the sides and 

 separated by a sharply defined groove at the sutures ; yours has the whorls a little convex in 

 outline and differently canaliculate at the sutures." Than Oliva myridiana, Duclos, this Challenger 

 shell is much larger, is different in colour and texture, and has a much coarser spire and apex. 



10. Oliva (Olivella) vitilia, Watson (PL XIII. fig. 8). 



Oliva (Olivella) vitilia, "Watson, Prelim. Report, pt. 12, Journ. Linn. Soc. Lond., vol. xvi. p. 342. 



Station 24. March 25, 1874. Lat. 18° 38' 30" N., long. 65° 5' 30" W. Off Culebra 

 Island, West Indies. 390 fathoms. Pteropod ooze. 



Shell. — Small, oval, glossy, with a short, blunt, subscalar spire, and in front blunt and 

 rather deeply sinuated. Sculpture scarcely any. Colour porcellanous. Spire very 

 short, roundedly conical, subscalar from the cylindrical rise of the whorls out of the 

 perpendicularly sunk sutural channel. Apex very blunt and rather large, impressed. 

 Whorls 5, very short, except the last, which occupies nearly the whole shell, rounded 



1 spd|U.iXXoj, a match for another. 



2 I.e., parallel to the axis, in which sense I would propose to use the word " axialfy."
