Hah. — Whangarei Heads, in 3-4 fathoms (C. Cooper). 

 This is the second species of the genus recorded from New Zealand 

 waters. 



MiTROMOEPHA GEMMATA, n.Sp. PI. VII, Fig. 18. 



Shell small, ovate, thin and fragile, semitransparent, white, axially 

 costate and spirally striate, the crossing-points gemmate. Sculpture : 

 all the whorls below the smooth protoconch are axially, equidistantly, 

 and closely costate, about eighteen on the last whorl, the interstices 

 narrow ; towards the base the riblets are getting obsolete ; they are 

 crossed by equidistant spiral cords of nearly equal strength, the points 

 of intersectien produced into transversely oval gemmules ; the inter- 

 stices between the spirals of about the same width as the cords, but 

 that below the first spiral is slightly broader and deeper than the 

 others; on the body- whorl there are about fifteen spirals, of which 

 the lowest six are smooth. Colour white. Spire elevated, conic; 

 outlines somewhat convex, but little higher than the aperture. Proto- 

 conch a little oblique to the axis, of one and a half smooth whorls, 

 the nucleus globose. "Whorls 6, the last high and somewhat ventricose, 

 convex, attenuated towards the base. Suture not deep, undulating, 

 bimarginate. Aperture slightly oblique, high and narrow, angled 

 above, with a rudimentary broad canal below, its base truncated. 

 Outer lip convex, thin, crenated on the outside by spiral sculpture, 

 with a shallow sinus below the suture. Columella subvertical, almost 

 straight, with two rounded, short plaits above, absent in young 

 examples ; inner lip thin and narrow, spreading over the straight 

 parietal wall. Operculum unknown. Diameter 3'1, height 7"2mm. 



Hah. — Near the Snares Islands, in 50 fathoms, type (Captain 

 J. Bollons); 24 miles south-east of Long Point, in 120 fathoms; off 

 south-east of Cape Saunders, in 100 fathoms (Edgar R. Waite). 



In form and sculpture somewhat resembling Baphnella vestalis, 

 Hedley. 



Bathytoma geatiosa, n.sp. PI. VII, Fig. 19. 



Shell very small, fusiform, white, thin, turriculate, spirally distantly 

 ribbed and with numerous axial threads. Sculpture : the spire- 

 whorls below the smooth protoconch have a fine thread margining 

 the suture below, a second very prominent spiral cord on the angle of 

 the shoulder, and a third equally strong cord at the middle between 

 the angle and the suture below ; the interstices concave and broader 

 than the cords ; body- whorl with six spirals from the angle down 

 toward the base, the upper three of which are strong, the others 

 closer together and not so high ; base with a few indistinct spirals. 

 Axial sculpture consisting of subequidistant fine threads, slightly 

 retrocurrent on the shoulder, flexuous further down ; on the body- 

 whorl they are becoming more irregular, fine growth-lines appearing 

 in the interstices. Colour whitish. Spire conic, turriculate, about 

 the same height as the aperture. Protoconch globular, smooth, of one 

 and a quarter whorls. Whorls 4, with a very distinct and but slightly 

 sloping shoulder; base somewhat contracted. Suture superficial,
