126 DR JAMES COSMO MELVILL AND MR ROBERT STANDEN ON THE 



C&rithiopsis macroura, sp. n. (Plate, fig. 13). 



C. testa elongato-fusiformi, parva, angusta, nitida, albo straminea, anfractibus ad 10, quorum apicales duo 

 vel tres nitidi, vitrei, perlaeves, bulbosi, cseteris paullum ventricosis, apud suturas imprcssis, undique longi- 

 tudinaliter arete costulatis, costulis anfractuum superiorum pro maxima parte Isevissimis, 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. 



Hob. Station 346, Burdwood Bank, 56 fathoms. 



A small 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 lirse, as are the lower whorls ; the 

 columella is only slightly rostrate, the outer lip thin, the colour whitish straw. But 

 few examples occurred. (/j-aKpog wpa, long-tailed.)

a-c (1908). 



Hab. Shore, Hearnden Water, Falkland Islands. Station 349. 



As mentioned in our first paper, we issued a description of this species in 1907, 

 using, at Dr H. STREBEL'S request, the name he had given it in manuscript. The 

 following year it was redescribed by him as " sp. nov.," 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 S. 



Family Turritellidse. 



Turritella algida, sp. n. (Plate, fig. 14). 



T. testa parva, attenuato-fusiformi, alba vel pallide straminea, solidula, anfractibus ad 9-10, ad suturas 

 multum impressis, quorum apex ipse bulbosus, albus, laevis, vitreus, huic proximus anfractus simili modo 

 tumidus, laevis, cseteris ad medium unicarinatis, carinis acutis, prominulis, antepenultimo et penultimo lira 

 alia minore infra medium prseditis, ultimo inter carinam majorem et basim trilirato, apertura ovata, labro 

 tenui. 



Long. 6, lat. 2 mm. 



Hab. Trawl, Burdwood Bank, south of the Falklands, at 56 fathoms. Station 346. 



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 lirations.
