QUEENSLAND MOLLUSC AN NOTES , No. 1.

script. I found, unfortunately, that many of tbe Australian forms needed 
discrimination and nomination, but here use the conventional terms only. 
Mr. C. Nicholson looked out for these molluscs for me at Oaloundra, and l am 
able to add two species to the Queensland list, viz., Jodina nilida A. Adams (Proc. 
Zool. Soc. (Bond.) 1868, p. 620, 1869: from 23 deg. N. 152 deg*. W. to off Tahiti, 
Pacific Ocean) and Violetta glob osa Swainson (Zool. Illus., vol. ii, pi. 85, 1826). 
The new genus name Violetta is introduced with globose as type, as this kind of 
Violet Snail differs very considerably from both Javihiua and lodina. 
For the Recluzia Medley used the specific name jolmii Chemnitz; this has 
been demurred to, and it will be undoubtedly better to use R. liar gravest Cox 
(Proc. Zool. Soc. (Lond,)', p. 172, pi. 16, f. 8, 1870) given to a New South Wales 
form. In the N.S.W. list Medley preferred hi tea Bennett, a name given to a 
tropical mid-Pacific form. 
Family NATICIDZE. 
The variety of species in this family, and the difficulty in separating them 
without series, compelled their intensive collecting whenever met with, delightful 
results thereby accruing. While more species will be added to the Queensland 
list when all the material is worked out, three may here be introduced: — (1) 
Natica gaidei Souverbie ( Journ. de Conch., vol. xxii, p. 196, pi. vii, fig. 7, April 
1, 1874: Lifu), which is a synonym of Natica line atom Jousseaume (Rev. Mag. 
Zool., ser. 3, vol. ii, p. 22. pi. ii, f. 5-4, 1874 (before April) : hah. unknown) and 
Natica notata Sowerby (Thes. Conch., vol. v, p. 83, sp. 44, pi. 462, f. 168, 1883: 
New Caledonia). The operculum is sulcate and thus it falls into Natica s. str. 
(2) Natica arachnoidea Gindin (Syst. Nat., pt. vi, p. 3674, 1791, for Chemn. 5, 
p. 271, pi. 188, f. 1915, 1916: locality unknown) was found alive with a notable 
brown velvety periostracum suggesting a distinct genus. 
When Iledley wrote upon “Some Natieoids from Queensland ” (Ree. 
Austr. Mus., xiv, pp. 154-162, 1924) he utilised fiber for the mammilla series 
with horny operculum, but indicated that groups could be utilised, observing: 
“Those species associated with fh pes-clcpltavtis, being large massive shells 
with a wide umbilicus containing a stout spiral funiele, may be grouped under 
Mammillaria Swainson.” Mamillarid was written by Swainson (Treat. Malac., 
p. 345, 1840), and M. lactca Sw. for Mart. 189, f. 1922, 1923, and this name was 
equal to Natica alba Gray 1827, and V. pes-ek pliant is Desha, yes 1838, the last- 
named being preferred by Medley, who included the species in the Queensland 
fauna on Schmeltz ’& record of a shell from Port Denison. It is pleasing, then, to 
report that Mr. Melbourne Ward collected a specimen on the beach at Friday 
Island, Torres Straits. Apparently the correct name to be used will be 
.1/ a miliaria alba Gray, as the superficies is very different from that of the true 
mammilla series. In the case of Mammilla Schumacher, the species show a very 
large animal not retractile into the shell as is the animal of pgriformis Recluz 
and flemingianum Recluz, two typical white “Eggshell Nerites” of the ancient 
writers. 
Gennaeosinum peleum gen. & sp. nov. 
( Pin te XXXI, fig. 12.) 
This very distinct form can be shortly described as a finely sculptured 
Natica or a Natieoid style of “ Siga retus.”
