Euthria subcallimorpha n. sp. (Plate XIX. figs. 2, 3.) 



Shell small, fusiform ; spire equal to or slightly longer than the aperture ; 

 sutures impressed, fairly deep ; whorls five, the apex missing, convex, the 

 last rounded at the periphery, thence gradually contracted to the canal ; 

 sculpture — there are eight low rounded axials, more pronounced on the 

 spire-whorls, feeble on the base of the last and vanishing towards the canal, 

 they are rather narrower than the interspaces ; the spirals consist of fine 

 close incised lines, forming lightly raised threadlets on the upper spire-whorls, 

 and with five or six on the canal more prominent. Aperture ovate, slightly 

 oblique, narrowed above, below produced into a short open canal ; outer 

 lip sharp and with a number of small denticles within the margin, columella 

 almost vertical, slightly callused, smooth, beak slightly twisted to the left. 



Length, 12 mm. ; width, 5-5 mm. ; length of aperture and canal measured 

 on the angle, 6 mm. 



Locality : Target Gully. Collected by Marshall. 



Type to be presented to the Wanganui Museum. 



The only example has the axial ribs somewhat rubbed. It may be 

 distinguished from callimorpha by the absence of the keel on the spire- 

 whorls, the shoulder not excavated, the finer spiral sculpture, and somewhat 

 longer canal. 



Hemifusus (Mayeria) goniodes Suter. 



N.Z. Geol. Surv. Pal. Bull. No. 5, p. 23, pi. 3, figs. 15, 16. 



Two examples of this species were obtained at Pahi and agree well with 

 Suter's description. The keel on the spire-whorls is well below the middle, 

 the shoulder sloping and concave, the sutures somewhat impressed, sub- 

 margined below and with a few small spiral threads, the spiral sculpture 

 is distinctly developed on the anterior end only ; growth-lines are some- 

 what prominent and appear to indicate a broad shallow sinus on the 

 shoulder. It appears doubtful if the genus Hemifusus is best suited for 

 the species, but better material is necessary to settle the question. 



Length (imperfect specimen), 63 mm. ; width, 27 mm. 



Locality : Pahi. Collected by Marshall. 



Eulimella awamoaensis n. sp. (Plate XIX, fig. 4.) 



Shell small, subulate, straight, and polished ; aperture about one-third 

 of the total length ; sutures distinctly channelled ; whorls eight ; the 

 apex of the protoconch broken, it is apparently oblique ; whorls flattened, 

 narrowly subangled a little below the sutures, most marked on the higher 

 whorls, the last narrowly curved on the periphery and convex below ; 

 sculpture consists of a number of irregularly-disposed feeble axial riblets, 

 spiral striae very indistinct ; aperture narrow above, outer lip straight, 

 columella rounded, narrow and straight, basal lip imperfect, apparently 

 somewhat produced. 



Length, 7 mm. ; width, 2-25 mm. ; length of aperture, 2 mm. 



Locality : Awamoa. Collected by Marshall. 



Type to be presented to the Wanganui Museum. 



Note. — In general form the species is near to E. limhata Suter. 



Odostomia (Pyrgulina) pseudorugata n. sp. (Plate XIX, fig. 5.) 



Shell small, elongated, narrowly turreted ; whorls seven, protoconch 

 smooth, heterostrophe, nucleus lateral, succeeding whorls slightly convex,
