&c. — Testa obtuse conoidea, plus minusve depressa, interdum 

 aureo-fulva, interdum olivaceo-viridis, infra leviter convexa, 

 imperforata ; anfractus convexo-declives, superne plicato- 

 corrugati, deinde granulati ; anfractus ultimus inferne obtuse 

 angulatus ; basis laevissime convexa seriatim granulata ; 

 apertura obliqua. Operculum ovale, exalbidum, vix con- 

 vexum, obsolete granulatum. — A very distinct and easily 

 recognised little species, which might be taken at first sight 

 for one of the Gibbula group of Trochus. — Hab. Australia. 



115. HENicus, pi. xii. f. 144, Watson, Moll. Challenger 

 Expedition, Linnean Society's Journal, vol. xiv. p. 703. — A 

 beautiful and remarkable new species, elaborately described 

 by the Eev. E. Boog Watson, B.A., F.L.S., &c. Not having 

 seen the shell, I do not venture to give a diagnosis, but the 

 accompanying figure will give a general idea of the species. 

 It partakes somewhat of the form and character of T. hcema- 

 tragus, but the sharp stellate keel is more like that of 

 T. latispina or auripigmentuTn, but differently placed. 

 The keel encircling the body whorl has about twelve sharp 

 hollow compressed spines, and below this there is a second 

 smaller keel, or sharp angle, to the base, with from thirty to 

 thirty-five vaulted scales, which towards the mouth become 

 spines ; in the space between the two keels there are four 

 rows of fine beads. — Hab. Matuka, Fiji, lat. 19° 10' S., long. 

 17y°40'E. 315 fathoms. Three specimens. 



116. aiBBEROsus, pi. X. f. 121, Chemnitz (Trochus), Conch. 

 Cab. vol. X. p. 287 — insequalis, Marty n — ochva.ceus, Philippi 

 — tentorium, Anton. — Testa late conica, imperforata ; an- 

 fractus circiter 7, convexo-declives, oblique creberrime striati, 

 superne costis parvis rugosis subnumerosis plicati, medio 

 granidis parvis 3-4-seriatim cincti, ad angulum carina 

 obsolete squamata vel undulata instructi ; basis ccmplanata, 

 leviter convexa, valide circulariter crenato-lirata, callo cen- 

 trali depresso ; apertura angulata ; columella obliqua. Oper- 

 culum oblongum percrassum, intus concavum, nigru-fuscum, 

 extvis valide convexum, albidum ferrugineo-tinctum, versus 

 marginem impressum. — A very characteristic species, not 

 easily mistaken. Though by no means rare, the shell is 

 seldom found in good condition, usually being much eroded, 

 especially towards the apex. The operculum is remarkably 

 thick and stony, and of a peculiar irregular oblong form. — 

 Hab. Lower California.
