fine lirse ; apex very acute ; aperture elongately fusiform, and 

 prolonged below into a rather long straight canal ; outer lip 

 thin, with a broad, deep incision (2-2- mil. broad, and 2 deep) ; 

 columella broadly enamelled. Long. 38, Lat. 12. 



Daphnella GEACiLLiMA. U.S. Shell fusifomi, thin, fragile, 

 shining, whorls 6, gracefully sloping, last longer than the spire, 

 finely striate lengthwise with irregular ridges of growth which 

 become fine, close, and rounded at the lip ; regularly and 

 somewhat distantly grooved with rather broad, flat, shallo-w, 

 conspicuously striate grooves, one of which is much broader 

 just below the suture, which is distinctly canaliculate ; apex 

 obtuse, and natica like ; mouth narrow, finely rounded at the 

 suture ; outer lip thin ; canal short ; base of the pillar finely 

 and obliquely decussate behind. Long. 21, Lat. 7|. Aperture, 

 Long. 13, Lat. '-i mil. 



This shell is vei*y closely allied to D. ornata, Hinds, of the 

 Philippines. It is very common in Table Cape. Fourteen 

 specimens were collected by Mr. Johnston. 



Daphnella tenuisculpta. n.s. Shell fusiformly ovate, 

 rather solid, aperture a little longer than the spire, apex 

 naticiform, depressed, smooth, shining, v/horls 6, rounded, 

 slightly concave and narrow, grooved near the suture, every- 

 where very finely and closely cancellated, acutely undulately 

 ribbed ; ribs broader than the lirse (which pass over them), 

 regular oblique, close on the -whorls of the spire, only slightly 

 interrupted by the groove, and becoming an obliquely sub- 

 granular on a margin round the suture. On the body whorl 

 irregular, fine and undulating, 24 in number; aperture pyri- 

 form, attenuate at each end ; outer lip thin, columella smooth, 

 canal somewhat short and truncate. On the basal whorl the 

 spiral liree alternate, lai'ge and small,' while the longitudinal 

 ones are much finer throughout. Long. 17, Lat. 8. Common. 



Mangelia gracililirata. n.s. Elegantly fusiform tur- 

 retted ; aperture about J length of spire, apex obtuse, smooth, 

 almost turbinate for 3| whorls ; the latter (apex included) 9, 

 convex, everywhere very finely Urate, lirse alternating regularly 

 large and small and obliquely plicate ; plaits 18, in penultimate 

 whorl, 23 in last becoming obsolete anteriorly Mouth 

 elliptical, outer lip varicose, produced in the middle, sinus in- 

 conspicuous ; columella grooved slightly ; canal short, truncate. 

 In larger and older specimens the former mouth leaves a dis- 

 tinct varix on the body whorl, half a turn form the lip. Long. 

 13, Lat. 5. Specimens much smaller than this are found, but 

 ■without the varix. 



This most remarkable fossil with its peculiar apex and varix 

 is distinct from any living or fossil known to me, though if I 

 mistake not there are Mesozoic forms not unlike it. I call
