Station 113a. September 1, 1873. Lat. 3° 47' S., long. 32° 24' 30" W. Anchorage 

 oft' Fernautlo-Noronha. 7 to 25 fathoms. Volcanic sand and gravel. 



Habitat. — West Indies. 



The Challenger obtained two fragments of an Oliva, which I believe to be this species, but I 

 cannot assign them to it without some doubt. 



Gray (loc. cit., p. 53) says that this is the Oliva pulchella, Eeeve, Conch. Icon., pi. xxx. fig. 98, the 

 Oliva onjza, Lam., Reeve, Conch. Icon., pi. xxvii. fig. 81, the Oliva menilifera, Eeeve, Conch. 

 Icon., pi. xxvii. fig. 84, and the Oliva pellucida, Reeve, Conch. Icon., pi. xxvii. fig. 85. Weinkauff 

 (loc. cit.), says it is the Oliva leucozonias, Gray, which Tryon denies. 



I have quoted the authorities given above, but can hardly believe they have all had the same 

 species before them.

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



p. 341. 



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

 350 fathoms. Eed mud. 



Shell. — Small, oval-oblong, glossy, white, with a short blunt spire, a conical base, and 

 a small oval mouth. Sculpture : Longitudinals — lines of growth very faint. Spirals 

 microscopic and obsolete. Colour porcellanous white, more or less transparent. Spire 

 short, convexly conical. Apex bluntly rounded. Whorls 4^, conical, barely convex, 

 with a minute sharp scalar projection below the suture. Suture minutely channelled. 

 Mouth oval, pointed and channelled above, slightly narrowed below. Outer lip sharp 

 and thin, patulous ; below, it projects in a blunt point on the right side, between 

 which and the pillar is the broad, open, shallow canal. Inner lip : there is a thick, 

 narrow, irregular-edged pad ; this in front coils round the pillar, which is bent, twisted, 

 short, truncated, and toothless. H. 0'15 iu. B. 011. Penultimate whorl, height 0-06. 

 Mouth, height O'l, breadth 0-07. 



In general size and proportions this a good deal resembles Oliva sprcta, Gould ; but that is 

 lower in the spire, the peripheral breadth lies higher, the shell is more attenuated in front, the 

 mouth is longer, and the pillar is more defined by a pad crossed at the point by two teeth.
