OF NEW SOUTH WALES. 



Bluraenbach {Nat Hist. p. 265) states that N. pulligera matui es 

 its offspring within the shell and carries them about with it, from 

 which circumstance the name '^ pulUgera^^ has been given. Miiller 

 (Verm. Terr, et Fluv. vol. 2, page 196), says that " the yellowish 

 white granules which frequently occupy the back of the shell are 

 the young of the Nerite as Rumphius shows. I have counted 235 

 in one specimen. But for the authority of Rumphius I should 

 have taken them to be the ovules of some wandering anamal- 

 cule." The following is the passage in full : — " Grana quce dor- 

 sum cochlece frequenter occupant^ esse ipsius Neritce puUos, Rumphius 

 docet ; horum ducenta triginta quinque in uno specAmine numeraviy 

 ovaliuj convexa, extus luteo alhida, intus alba, moleculis referta, cor- 

 puscula hcec scejoe ahsterguntur, remanente in testa circulo ovali alho' 

 Nisi obstaret auctoritas exactissimi Rumphii ovtda peregrini anim- 

 alcuU putarem." 



Melania oncoides. n. s. 

 M. t. fusiformi turrita spira elata, decollata, periostraca palli- 

 dissima lutea aliquando induta, lineis rufis, imdulosis longitudina- 

 liter insignita ; anfr. 6, convexis, declivibus, liris spiralibus quatuor 

 regulariter cinctis, in spira liris nodosis et oblique subplicaiis, sutura 

 bene itnpressa ; apertura oblong o-ovata, antice effusa, labro acuto, 

 labio calcareo. 



Long. 20, lat. 10, long, aperfc. 9, lat. 7. Common in the creeks 

 near Bourke, Darling River. James Ramsay. 



Shell fusiformly turretted, spire produced, decollate, sometimes 

 covered with a very pale yellow periostraca, marked longitudinally 

 with red undulating lines ; whorls 6, convex sloping, regularly 

 spirally girdled with four lira3 ; in the spire the liras are distinctly 

 nodose and obliquely subplicate, suture well impressed, aperture, 

 oblong ovate anteriorly effuse, labrum acute, lip chalky. 



This Melania comes very close in form and coloring to 

 M. onca, Angas, which is found in the fresh water streams about 

 Port Darwin, N. Australia. The difference in this species are:- 

 1. It is much smaller. 2. Conspicuously Urate. 3. The plaits 

 are almost obsolete and rarely seen, except on the upper whorls.
