17. Turritella philippensis, Watson (PI. XXX. fig. 6). 



Turritdla philippensis, Watson, Prelim. Report, pt. 6, Jomn. Linn. Soc. Lond., vol. xv. p. 223. 



Station 161. April 1, 1874. Lat. 38° 22' 30" S., long. 144° 36' 30" E. Off entrance 

 to Port Philip, South, Australia. 33 fathoms. Sand. 



Shell. — A narrow cone ending a little abruptly in a sharp point, profile lines straight, 

 base angulated and flat, of a suffused brown colour with longitudinal brown flecks. 

 Sculpture: Longitudinals — fine, numerous, close, much -curved lines of growth. Spirals 

 — there is a slight angulated swelling at the top and bottom of each whorl (that at the 

 top being rather nearer the suture than that at the bottom) ; between these the surface of 

 the whorl is slightly concave, with a flat feebly projecting band in the middle, the upper and 

 lower edge of which is defined by a spiral thread ; besides these spirals, which are absent 

 in the upper whorls, the whole surface is marked by irregular and unequal narrow and 

 almost obsolete spiral threads, which are stronger on the base. The generic microscopic 

 spirals are strong, but without delicacy or depth. Colour ruddy light brown, with darker 

 longitudinal curved flecks ; ou the upper whorls the centre of the whorl is coloured and 

 the top and bottom is white ; the three apical whorls are porcellanous white. Spire per- 

 fectly conical in its profile lines. Apex : the last whorl contracts suddenly and rises in a 

 fine rounded, but almost sharp point. Whorls 11 ; but the shell is not full-grown. They 

 are almost flat on the sides, with a slisrht angular contraction into the suture above and 

 below ; the flat base is angulated at the edge and is a little conical Suture is slightly 

 impressed by a shallow broadish angular depression. Mouth, outer and inner Up, and 

 pillar are not fully developed. The generic sinus is parabolic in shape. H. 0'61 in. 

 B. 0-19, least 0'17. Penultimate whorl, height 012. Mouth, height 0'13, breadth O'l. 



This species is somewhat like Turritella sinuata, Reeve, but is a narrower shell with higher 

 whorls, which are less convex ; the apical whorls are much larger, and the apex itself sharper and 

 more prominent. 



18. Turritella (Eglisia) tricarinata, Adams and Reeve. 



Eglisia tricarinata (not Turritella tricarinata, Brocchi, nor that of King), Adams and Reeve, " Sama- 



rang," 1840, p. 49, pL xii. fig. 8. 

 „ ,, Reeve, Conch. Icon., vol. v. pi. i. fig. 3. 



Station 212. January 30, 1875. Lat. 6° 54' N., long. 122° 18' E. Off Malanipa 

 Island, Basilan Strait, Philippines. 10 to 20 fathoms. Sand. 



Habitat. — China Sea (Adams and Reeve). 



It did not seem right to disturb this name, but it is obvious that if Eylisia is to reckon merely 

 as a subgenus the specific name cannot be retained in the face of its previous use by Brocchi and by 

 Bang for two quite different species of Turritella.
