OF NEW SOUTH WALES. 126 



The next species is a very small shell from Victoria, closely 

 resembling H. mucosa Cox of N.S.Wales. 



Helix mucoides, n.s., Ph 12, fig. 5, 5a. 



H. t. minuta, late umbilicata, depressa, orhiculata, vix discoidea, 

 solidiuscula, nitente vel quasi oleo inuncta, crehre corrugata, vel 

 irregulariter striata, corneo-lutea, unicolor, translucens. Spira 

 exserta, apice prominulo, ohtuso. Sutura hand impressa. Anfr. 4|-, 

 rotundatis, sensim accrescentibus, idtimo superne planato et obtuse 

 carinato. Basi coQivexa, ut supra rugose striata sed subtiliori, et 

 (suh lente tantum visis) subtilissime creberrimeque spiraliter liratis. 

 Umbilico eprspectivo, vix | diam. testes cequanti. Apertura sub- 

 quadrata, intus pallidissime cceruleo-albida. Peristoma simplici, 

 marginibus obtusis, haud approximatis, columella parum expansa et 

 reflexn. Testa maculis fuliginosis magnis et irregularibus plus 

 minusve insignita. Forma et colore H. mucosa proxima, minuta 

 vero et inconspicua. Diam. maj. 3, min. 2 J, alt. IJ millim. 



Shell minute, widely umbilicate, depressed, orbicular but hardly 

 discoid, rather solid, shining as if from oil, very closely corrugated 

 or irregularly striate, yellowish horn, of one uniform color and 

 translucent. Spire exsert, apex slightly prominent, obtuse. 

 Suture not impressed. Whorls 4|, rounded, increasing gradually, 

 the last flat above and obtusely keeled. Base convex and 

 rugosely striate as above, but more finely, and under the lens seen 

 to be closely, very finely spirally lirate. Umbilicus perspective, 

 scarcely J the diameter of the shell. Aperture subquadrate, a 

 very pale blueish white within. Peristome simple with obtuse 

 margins which are not approximate. Columella slightly expanded 

 and reflected. The shell is more or less marked with large 

 irregular sooty patches. 



H. mucosa, which it resembles is a very rare shell, but much 

 larger, and the rugose striae are proportionately much smaller. 

 With this shell was associated H. melbournensis Cox, and 

 JET. juUoidea Cox. The latter is a Tasmanian species, but I could 

 see no appreciable difierence between the Melbourne specimens 

 and those coming from Mount Wellington.
