CANTHARIDUS PRUNINUS. 



Cantharidus pruninus, Govild ; Pilsbry, Mau. Conch., Vol. XL, |). 122, PI. XLVL, 

 figs. 60, 61 ; PI. XXXIV., fig. 1, vnv. j>erobtusa. 



var. minor. Testa minima. Longit. 8 mm., diam. maj. 6| mm., min. C mm. 



Habitat. — Auckland Islands, 10 fathoms. 



A few specimens were obtained, which, although apparently adult, 

 are not a quarter the size of other examples from the Auckhmds. 

 In form, colour, and sculpture, however, they are quite similar. The 

 species also occurs at Campbell Island. 



CALLIOSTOMA AUCKLANDICUM. 



(Pi. XXIV., fig. .5.) 



Testa parva, conica, obtecte umbilicata, roseo-purpurea ; anfractus sex, primus laevis, 

 convexus, involutus, pallidiis, vel flavescens, caeteii levissirae convexi, liris 

 spiralibus tenuibus roseo-pmpureis cincti, infra suturam nodosi vel subplicati, 

 striis incrementi obliquis confertis concinne sciilpti, ultimas ad peripheriam 

 angidatus, infra concentrice liratus, in medio excavatus et albus; apertura 

 subquadrata, margaritacea, laevis; peristoma ad marginem acutum, roseo- 

 lirabatum, intus leviter incrassatum ; columella alba, subobliqua, superne leviter 

 reflexa, antice subdentata. 



Diam. maj. 8 mm., min. 7 mm., alt. 7^ mm. 



Operculum tenue, corneum, multispirale. 



Habitat. — Auckland Islands, 10 fathoms. 



The general tone of this species is purplish-rose, but under the 

 lens the narrow sulci between the spiral lirae are dirty whitish, and 

 the small umbilical excavation is also white. The spiral threads 

 increase in number upon the whorls with the growth of the shell, 

 there being about eight upon the penultimate, the uppermost, or that 

 just below the suture, being somewhat nodose or subplicate. The 

 body-whorl has eight lirae above the angle and ten or eleven below. 



PHOTINULA EXPANSA. 



Photinula expansa (Sowerby) ; Pilsbry, Man. Conch., Vol. XI y> 279 

 PI. XXX IX., figs. 51, 52. 



Habitat. — Cape Adare, 24 fathoms. 



One very young specimen (3^ mm. in diameter), at which age 

 there is a small umbilical perforation, but the reflection of the 

 columella has already commenced. This species is also known from 

 the Straits of Magellan, Falkland Islands, South Georgia, and 

 Kerguelen Island.
