290 REV. R. BOOG WATSON ON THE 



This very pretty little species is very like A. glaber, Eve., but 

 has a higher and sharper spire, a much feebler, less channelled 

 suture, and lacks the sculpture on the upper whorls, which in 

 A. (£.) glaher are harshly pitted up to the very apex. These 

 three smooth apical whorls are very peculiar, and distinguish 

 the ' Challenger ' species from A. (_B.) strigosiis, Gould, from 

 Japan, the coarse apex of which is strongly sculptured. In 

 that species, too, the upper tooth on the pillar is very feeble *, 

 My note on the British-Museum Buccinuli was that some of 

 them seemed not well individualized, especially in the case of 

 the various specimens of A. glaher, E-ve., A. affinis, A. Ad., 

 and A. fumatus, Eve., and, further, that A. cinereus, Wats., 

 seemed to agree with two specimens of A. glaber on different 

 tablets, the one from Fiji, the other from " Sandy Cape." Mr. 

 Edgar Smith, who kindly compared the species for me, confirms 

 this opinion. Writing on May 2, 1882, he says : — " We have 

 this shell marked A. glaher, var., from Japan ; but it is probably 

 distinct from that species."

Shell. — Minute, ovate, subelongate, pointed, spirally striate 

 from end to end, with slightly canaliculate and submarginated 

 suture and a large mouth. Sculpture. Longitudinals — there are 

 very slight hair-like lines of growth. Spirals — the whole shell is 

 scored with strougish deepish distant little furrows, which are 

 rather more remote above than below the periphery ; the first 

 one below the suture is a little stronger than the others. Colour 

 glossy translucent white. Spire rather high, conical, regular 

 scalar. A^ea; small, rounded, the small tip being very little 



* This obseryation of mine does not agree with that of Lisclike, who in his 

 ' Japanische Meeres-Conehylien,' 2ter Theil, p. 104, pi. t. f. 13, 14, says, " von den 

 beiden Falten der Spindel istdie obere massig." As he describes the lower one, 

 however, as " sehr Xraftig," one may recognize from his figure that both expres- 

 sions rather exaggerate the features they describe, and that his description of 

 the upper tooth as " middling " is not materially different from my " feebler."
