vel tres nitidi, vitrei, perleeves, bulbosi, ceeteris paullum ventricosis, apud suturas impressis, undique longi- 
tudinaliter arcte costulatis, costulis anfractuum superiorum pro maxima parte levissimis, quatuor ultimis 
anfractibus spiraliter rugoso-liratis, liris ad juncturas costularum granulosis, apertura ovata, labro tenui, 
columella paullum producta, flexuosa, brevirostri. 
Alt. 3°55, diam. 1 mm. 
Hab.—Station 346, Burdwood Bank, 56 fathoms. 
A smal] species, but distinguished, as the specific name chosen would show, by 
its very attenuate, fusiform whorls, the last three or four swollen, caudate, shining, 
smoothly costulate, not spirally crossed with granose lire, as are the lower whorls; the 
columella is only slightly rostrate, the outer lip thin, the colour whitish straw. But 
few examples occurred. (maxpos ovpa, long-tailed. )

As mentioned in our first paper, we issued a description of this species in 1907, 
using, at Dr H. Srrepew’s request, the name he had given it in manuscript. The 
following year it was redescribed by him as “ sp. noy.,” and we are of opinion that he 
had not at that time seen our paper. ‘The same remarks would apply also to Trophon 
minutus, M. and 8.

Very small, but apparently quite adult. Conspicuous for a distinct and prominent 
median keel, the three last whorls also being provided with a minor spiral lira below, 
and the body whorl, between the strong median keel and the base, possessing three such 
spiral lations.
