not uncommon in the beds above mentioned, where we have failed to find 

 examples of the Recent species. 



Length, 125 mm. ; width, 47 mm. 



The series of specimens here noted to be lodged in the Wanganui 

 Museum. 



Fulguraria (Alcithoe) turrita var. nukumaruensis n. var. (Plate IX, 



figs. 18, 19.) 

 Distinguished from the species by its more slender form, the absence of 

 prominent nodules, the axial riblets being feeble and almost absent on 

 the last, the body having the same fiat slope as the whorls above. 

 Length, 102 mm. ; width, 34 mm. ; length of aperture, 57 mm. 

 Locality, Nukumaru. 



Type to be presented to the Wanganui Museum. 

 There are several specimens, of which only one is perfect. 



Fulguraria morgani n. sp. (Plate VII, figs. 12, 12a, 126.) 



Shell rather small, narrow, axially costate, spire turreted. Whorls six 

 or seven, lightly shouldered above the middle, excavated or flattened above 

 the shoulder, below slightly convex, the last whorl slightly tapering to the 

 anterior end ; the protoconch consists of ai)out two and a half smooth 

 whorls, somewhat rounded, apex blunt, the first half-turn somewhat laterally 

 disposed by a comparatively wide and deep sutural excavation. Axial 

 riblets sixteen to nineteen, rounded, rather narrower than the interspaces, 

 usually less pronounced above the shoulders and on approaching the 

 anterior end of the last whorl, on the latter towards the lip somewhat 

 variable. Sutures undulating, not deep. Aperture slightly oblique, narrow, 

 almost canaliculate above ; outer lip with sharp margin, slightly curved to 

 the anterior end, the latter rather broad and deeply notched ; columella 

 almost straight, lightly twisted at the anterior extremity, thinly callused 

 and with four plaits, the lowermost occasionally feeble. 



Length, 47 mm. ; width, 17 mm. ; length of aperture, 28 mm. 



Locality, Waipipi, in blue sandy clay. ^ 



Type to be presented to the Wanganui Museum. 



Originally an example of this species was submitted to Captain Hutton, 

 who pronounced it Voluta corrugata, Miocene. It was said to occur in 

 the Patea or Waverley district, but the exact locality was unknown. On 

 comparing it with the description and figures given by Suter {N.Z. Geol. 

 Surv. Pal. Bull. No. 2) it was' apparently quite different from Hutton's 

 species ; we therefore submitted examples to Mr. P. G. Morgan, Director 

 of the Geological Survey, for comparison with the types, and his report 

 coincides with the opinion we had formed. Its nearest kin is perhaps 

 F. gracilis Swains. We convey to Mr. Morgan the compliment of associat- 

 ing his name with the species. 



Turris curialis n. sp. (Plate VII, fig. 14.) 

 Shell narrowly fusiform ; spire turreted ; whorls with sloping flat 

 shoulders bounded by a prominent nodular ridge ; thence to the suture 

 below excavated ; the concavity below the ridge continues across the 

 body-whorl immediately above the aperture and appears again on the 

 lip strongly marked (shell partly embedded in the matrix), anterior to 

 this slightly convex, thence gradually contracted to the canal. Whorls 

 probably eight or more. Sculpture : Several small spiral threadlets between 

 the suture and keel, and two somewhat stronger between the latter and
