1. Cyllene oblonga n. sp. PI. XXII, fig. 10. 



Stat. 153. o''3'.8N., 130° 24. 3 E. Bougainville-Strait. 141 AI. Fine and coarse sand with dead 

 shells. 5 Spec. 



Shell elongately-ovate, with rather short, acute spire. Whorls 7, of which the upjjer 2 nuclear 

 ones are smooth, subsequent whorls concave at the upper part, with a row of tubercles just 

 above the distinct, undulated suture, the 4^'^ and 5''^ whorl are ribbed and these ribs are tubercled 

 below, the tubercles becoming however less apparent and disappear at last on the penultimate 

 whorl, these two whorls are crossed by spiral striae, about 5 in number, in the concave part, 

 last whorl large, slightly concave above, with fainter ribs below the suture, nearly disappearing 

 on the lower part, with the spiral striae as in the penultimate whorl and a few spiral striae 

 below (inconspicuous in some specimens). Aperture elongate, with a sharp angle above, passing 

 in a short channel, running along last part of suture, outer margin thick, yellowish, with a 

 strong, white labial rib externally and about 20 conspicuous lirae in the interior; basal sinus 

 conspicuous; columellar margin with a transparent layer of enamel, smooth above with conspicuous 

 wrinkles below, where its limit is marked by a sharp brown line, canal short but broad. Colour 

 yellowish brown, with irregular white spots on the upper whorls ; last whorl with three zones 

 of white spots, base of shell white, interior of aperture brown.

This species resembles in shape C. ptclchella Ads. and Reeve, as figured by Sowerby 

 (Thes. Conch. Vol. Ill, Cyllene PI. 217, fig. 24, 25), but is still narrower and quite different 

 in colour. In colour-pattern, but not in colour it resembles C. glabrata Ads. ; these observations 

 are based however, on the rather rude figures of the Thesaurus. The shells are empty, but 

 the described typical specimen is quite fresh, so it may have lived at the recorded depth. 



2. Cyllene Sibogae n. sp. PI. XIX, fig. 7. 



Stat. 98. 6°9'N., i20°2l'E. Sulu-archipelago. 350 M. Sand, i Spec. 



■ Shell elongately-ovate, with moderately long spire. Whorls nearly 6 (nucleus wanting) 

 angtilar, upper half concave, lower half nearly straight, last whorl contracted below, consequently 

 more convex; uppermost whorls slightly tuberculate below the conspicuous, undulate suture, 

 which is canaliculate in ultimate and part of penultimate whorl; the whorls are crossed by
