CHLANIDOTA, COMINELLA. 201 



Y. FlSCHERIANA, A, Ad. 



An unfigured species said to be " intermediate in form between 

 V. ampullacea, Midd., and V. Perryi, Jay. It is a thinner and 

 smaller shell, with a hispid epidermis, the short hairs being 

 arranged in close-set cross rows, giving the surface a reticulated 

 appearance." Length, 1 inch, diam., 11 lin. 



Korea Strait, South Japan. 



Unfigured. Probably not distinct from Ampullacea. 



V. LIMN^EANA, A. Adams. 



This name is in the list of species of Bullia in the Genera of 

 Recent Mollusca, and is mentioned subsequently as a Volutharpa 

 in Ann. Mag. N. Hist., 1860. I do not find any description of it. 



Y. MORCHIANA, Fischer. 



This is believed to be synonymous with Buccinum cyaneum, 

 Brug. 



Genus CHLANIDOTA, Martens. 



C. VESTITA, Martens. PI. 79, fig. 391. 



Epidermis yellowish brown ; shell white. Length, 23 mill. 



Kerguelen Island. 



Genus COMINELLA, Gray. 



Kobelt has recently published a systematic catalogue of the 

 species of this genus, in which they are carefully arranged in 

 accordance with their inter-relationships. I have followed it ; 

 merely reducing the number of species which he admits, and 

 adding a few which appear to have escaped his notice. The 

 genus is confined in its distribution to the Southern hemisphere, 

 the metropolis of the typical species being New Zealand ; 

 although a few are found at the Cape of Good Hope, etc. 

 Martens' subgenus Ghlanidota does not appear to me to be very 

 closely related to Cominella, and I have preferred to treat that 

 shell as a genus. Kobelt includes the species of Amphissa, but 

 the thickening and dentition of the outer lip, the absence of the 

 posterior constriction and general facies, as well as lingual 

 ribbon, indicate a closer relationship with Columbella. I have
