“Chrysodomus (Sipho) crassicostatus, sp. n. (Plate, figs. 10, 10a).
C. (Sipho) testa parva, ovato-fusiformi, solidula, albo-cinerea, periostraco tenui olivaceo-stramineo contecta, anfractibus 5-6, quorum apicales 2-3 gradati, subhyalini, cæteris spiraliter crassicostatis, apud suturas impressis, ventricosis, ultimum apud anfractum numero 7, interstitiis lævibus, apertura ovata, labor paullum effuso, columella excavata, ad basim breviter truncatula.
Long. 6, at. 3 mm.
Hab.—Station 325, Scotia Bay, South Orkneys, 9-10 fathoms, off weed and stones, April–August 1903.
A very compact little species, of which a few examples, all precisely similar in size and sculpture, occurred. It is likely they are nearly, if not quite, adult, and are conspicuous for the strong, acute spiral liræ or riblets encircling the three lower whorls in a uniform fashion, there being seven on the body-whorl.
