390 A NEW GENUS OF CARNIVOROUS SNAILS, 



teeth of my illustration are seen, those to the right pressed down 

 on their right side and those to the left on their left. Viewed 

 perpendicularly, the teeth appear straighter and narrower, pre- 

 senting much resemblance to those figured and described for 

 Rhytida lampra. The pharynx is enormous, occupying almost 

 the whole length of the visceral cavity and nearly equalling in size 

 the remainder of the viscera. The small stomach overlies it and 

 leads to a short intestine which after passing close to the heart 

 reaches the anus at the mantle margin. From the posterior end 

 of the pharynx a muscle proceeds to the shell-muscle. A long 

 contorted toot-gland runs the length of the floor of the visceral 

 cavity, originating beneath the mouth and terminating in a knob 

 within the tail. 



The genital apparatus is of the simplest description. The penis- 

 sac is more reduced than in any mollusc with which I arn 

 acquainted, appearing to be represented by a slight bulbous 

 swelling near the orifice, a vas deferens arising therefrom, and a 

 short muscle attaches this swelling to the nearest point of the body 

 wall. I found no spermatheca. A complete egg in the oviduct 

 of one specimen dissected proved the maturity of the animal, and 

 the agreement of three specimens examined attested the uniformity 

 of this remarkable system. Mr. Murdoch found the eggs to be 

 laid in the month of August; he states that "The eggs were 

 found principally under a good thickness of decaying fern leaves, 

 and were in little heaps of from six to as many as fourteen." 

 These eggs are white, hard-shelled, oval, 4 mm. major axis, 3 mm. 

 minor axis, coarsely granular without, smooth within. The 

 embryo in one I opened was in an early stage of development and 

 had not yet acquired any recognisable molluscan features. 



Summary. — On the evidence of the naked shell, {D.) novosee- 

 landica, Pfr., was referred to Daudehardia, otherwise exclusively 

 a Pal^earctic genus. At the first glance the soft parts appear to 

 confirm this determination. Closer scrutiny, ho^vever, strengthens 

 the suspicion* aroused by the supposed exceptional distribution. 



*Kobelt (Jahrb. Deut. Mai. Gesell. vii. p. 26) and Fischer (Man. de 

 Conch, p. 256) both catalogue this species as Daudthardia {?) novo^edandica.
