302 Transactions. 



small, close, and more distinct growth-periods mark the position 

 of successive lip-margins. Colour yellowish-horn, white under- 

 neath the epidermis, which is very thin, microscopically deli- 

 cately roughened, which obliterates almost all trace of gloss. 

 Spire conoidal, with a blunt apex. Protoconch rounded, obtuse, 

 but its character is obscured by foreign growth upon it. Whorls 

 4, rapidly increasing, slightly convex, the last comparatively 

 large, with a few longitudinal light swellings. Suture impressed, 

 not deep. Aperture oblique, large, squarish. Outer lip sharp, 

 inflexed above and strongly angled at the periphery, reaching 

 the pillar in a slight curve and at a right angle to it. Inner lip 

 forming a narrow rounded callosity over the but -little-excavated 

 columella, which ends in a point at the base and forms a small 

 but distinct notch with the outer lip, which is slightly thickened 

 in the proximity. Altitude, 3 - 83 mm. ; diameter, 3 29 mm. 



Obs. One empty specimen of this curious shell was obtained. 

 Mr. Hedley thinks it the greatest puzzle of the whole collection, 

 and he offers two suggestions — (1) that it is a larval shell ; 

 (2) that, if adult, it may represent a new genus near Ianthina. 

 We are more inclined to consider it as a larval shell. The 

 colour and presence of an epidermis remove it from Ianthina, 

 but they would not exclude it from Rechczia. However, the 

 distinct angle of the outer lip and the but slightly convex whorls 

 are somewhat inconsistent with that genus, of which the young 

 forms are unknown to us. Unfortunately we do not know the 

 animal. We publish description and figures in the hope that 

 some scientist may give us a clue to the true generic position. 



57. Ancilla, sp. 



A number of specimens of an apparently new species were 

 obtained, but none of them is perfect, and it is impossible to 

 describe them. The species is very small ; length, about 5 mm. 



58. Typhis, sp. 



A very poor specimen turned up. It may be T. yatei, C. 

 and F., but it is much smaller than that species, and in too bad 

 condition for identification. It certainly is not T. Zealand ica, 

 Hutt. 



59. Solarium, sp. 



A fragment only. 



60. Siphonalia, sp. 



A number of small dead shells, but they seem too young to 

 deal with.
