Cominella elongata. Pl. xviii., fig. 5. . 
Shell elongated, the spire acute and much longer than the aperture. 
Whorls 8, the first 24 embryonic, polished ; the next 3 or 4 with about 10

lines, and, after the fourth or fifth whorl, some distant shallow grooves, of vens 
which there are about 9 on the body whorl. Aperture ovate, the posterior |
