388 A NEW GENUS OF CARNIVOROUS SNAILS, 



novoseelandica, the shell but not the animal of which he knew. 

 Complete specimens from the same source proved later (Op. cit. 

 "Vol. XV., p. 140) to be a species of Testacella. 



Mr. Brazier, having recently received from Mr. R. Murdoch, of 

 Wanganui, N.Z., specimens of this mollusc collected by that 

 gentleman near Stratford, a township inland from Mt. Egmont, 

 has, most liberally, placed these treasures at my disposal for 

 dissection and description. These animals had, I understand, been 

 carefully drowned in water before being placed in alcohol, and 

 probably present a tolerable resemblance to the living snails. 

 Their external appearance is quite suggestive of the European 

 carnivores Daudebardia and Testacella; the rudimentary shell 

 quaintly perched on the creature's tail, the auriform shape of that 

 shell and the aculeate teeth of the radula all combine to present a 

 strong, but I am persuaded a superficial and misleading, likeness 

 to their antipodean representatives. Closer examination detects 

 differences in every detail. Comparing the pulmonary orifices : 

 that of Schizoglossa is seen, as depicted in my sketch, located in 

 the usual antero-lateral margin of the mantle. To contrast with 

 this, I have copied on my plate fig. 9, pi. v. of Moquin-Tandon's 

 " Histoire Naturelle des Mollusques terrestres et fluviatiles de 

 France," showing the totally different and remarkable position of 

 the same orifice {/) in Testacella. I am unacquainted with any 

 illustration of the foramen of Daudebardia, but suppose it to be 

 similarly placed, because Fischer says of it (Journ. de Conch, v. 

 1856, p. 16), "Behind there opens obliquely the respiratory pouch, 

 which is rather large and extends opposite the point of the foot." 

 The grooves that run outwards and downwards from the shell 

 along the body in the European genera are wanting in Schizoglossa. 

 The shells of the three genera under discussion are quite dissimilar, 

 the New Zealand shell standing alone as to its remarkable little 

 pit, excavated for the reception of the shell-muscle; a feature more 

 resembling the ligament-pit of some bivalves than an ordinary 

 columella muscle-scar. 



Contracted in alcohol, S. novoseelayidica is in length 20 mm., 

 in height and breadth 9 mm. Behind the shell, situated upon
