218 MR. T, D. A. COCKERELL ON THE [Apr. 7, 



External genital orifice on a pale patch, below and slightly anterior 

 to respiratory orifice. No regular dorsal grooves. 



Genital orifice from head 13, from respiratory orifice 5, from sole 

 2| millim. Respiratory orifice from head 16, from genital orifice 5, 

 from sole 7 millim. 



Described from a specimen in the British Museum, from the south 

 side of Cook's Straits, New Zealand {Wellington Museum). 



Hyalimacince. 



Contains the genus Hyalimax, H. & A. ild., with one species in 

 the Andaman Is., one in the Nicobar Is., one in Bourbon, two in 

 Mauritius, and one only on the Asiatic mainland — H. viridis Theob., 

 of Pegu. 



Succineines. 



The typical but testaceous genus Succinea is widely distributed in 

 both hemispheres. A slug-like genus, Omalonyoo, d'Orb, is found 

 in Trinidad, British Guiana, Brazil, and La Plata, and reported also 

 from Guadeloupe and Juan Fernandez. A specimen in the British 

 Museum from Pernambuco {H. N. Ridley) may be O. patera, 

 Doring ; it is paler and less marked than O. unguis, Fer. 



VaginulidjE. — Veronicellince. 



This subfamily consists of the genus Veronicella, Blainv. 

 (Vaginula, Fer.), with very numerous species in tropical regions, 

 and the monotypic genus or subgenus Leonardia, Tapp.-Can., 

 which differs in the more posterior position of the female genital 

 orifice. The genus Veronicella consists of about 133 species, distri- 

 buted as shown on pp. 219-220. The correct numbers cannot be 

 exactly ascertained, as it is probable that some of the species will prove 

 synonymous with others, while others may have to be placed in dis- 

 tinct genera \ It is also probable that many species remain to be dis- 

 covered. The numbers given for each country, added together, make 

 more than the total of 133, owing to the fact that several species 

 inhabit more than one country. As a rule, however, the species have 

 not a wide distribution ; very many are peculiar to islands. There 

 are no species in the Paleearctic or Nearctic Regions, the occurrence 

 of V.fioridana in Florida being merely an indication of the West- 

 Indian affinities of the fauna of that State ; while the anomalous fact 

 of a species {V. scMvelycB, Pilsbry) in I5ermuda seems to find its 

 explanation in the probable introduction of the Bermuda species 



1 For example, I have recently examined specimens in the British Museum 

 from the Neotropical region which seem worthy of at least subgeneric distinc- 

 tion, namely a species from Eio Janeiro referred to V. taunaysi, Fer., and the 

 true' Veronicella Icsvis, Blainv., from Jamaica. Ferussac's name Vagimda may 

 he used for the former, and thus we get : — 



(1) Veronicella, Blainv. Sole narrow, rounded and not projecting beyond 

 mantle posteriorly. Female genital orifice post-median. (Type, V. Icevis, 



Blainv.) . , • , 



(2) Vaginula, Fer. Sole broader, projecting beyond mantle posteriorly. 

 Female genital orifice antemedian. (Type, V. tamiaysi, Fer.)
