distinct entities known under these two names in Queensland, whatever else 
may be the ease. The larger form ( limacina ) is smooth with large spotting and 
pustules evanescent on the back, the median line being more or less ill- defined ; 
the smaller shell (staphyhm) has strong pustulation, the groove on the back 
deep and very notable; the face, however, separates the shells easily, as in the 
small species the teeth extend right across the base, whereas the large shell has 
the teeth confined to the edges of the. aperture, a white callus developing laterally 
on both sides; the teeth appear to number one or two more in the smaller species 
with more intercalating ruga*; the base, moreover, is entirely brownish red, while 
on the large species it is white, the teeth brown, the intervals between the teeth 
cream. I found the small species on Michaelmas Cay and Low Island only, the 
animal being black, dotted with white. Garrett says the animal of limacina is 
vermilion. 
Xenuroturris legitima gen. & sp. nov. 
(Plate XXXI, figs. 3, 4.) 
When Hedley published his Revision of the Australian Turridse (Ree. 
Austr. Mus., vol. xiii, pp. 213-359, 1922) lie commented (p. 217) : “T. spectabilu 
and T. garnonsi Reeve form a pair differing in the length of the canal. Similar 
pairs are T. tigrina Lamk. and T. abbrcvtata Reeve; T . warm oral a Lamk. and 
T. cingulifera Lamk.” The former series have a long canal, the latter a short 
one, and by a peculiar coincidence none of the latter series had been reported 
from Australia when Hedley wrote. I was therefore delighted to meet with the 
present species washed up alive on the beach at Michaelmas Cay. It agrees with 
shells called T. cinguhferah am., but does not agree with Lamarck’s description, 
which was from unknown locality, and specimens so determined prove very 
different from Mauritius and Polynesia. 
Shell large, awl-shaped, mouth small, canal short and broad, fasciole deep, 
distant from the suture, and followed by a strong ridge which is composed of 
three line. Colour creamy white thickly dotted with pale red-brown spots, the 
raised ridge being ornamented by darker regularly spaced blotches. Sculpture 
consists of fine concentric lira? ; on the antepenultimate whorl half a dozen can 
be counted above the ridge and a dozen below, four being more prominent; the 
last whorl shows the same sculpture throughout, seven line predominating; 
longitudinal sculpture scarcely observable save with a good lens. Columella 
nearly straight; inner lip with a very thin glaze extending across the body 
whorl ; outer lip rather straight from tin* suture to the fasciole then from below 
the fasciole sweeping forward, then recurring to short open canal. Length 
57 mm.; breadth 18 mm. Much larger specimen measures 72 x 23 mm. The 
operculum is leaf-shaped, thick, horny, apex terminal; differing considerably 
from that of Asthcnotoma as figured by Hedley (Rec. Austr. Mus., vol. xiii, 
pi. xiii, f. 4, 1922) and from that of Turris, described as unguiculate. The short 
canal obviously differentiates the group generically. 
Family MITRLChE. 
The most troublesome groups of mollusca to-day are those of the best 
known shells such as Cones, Cowries, Mitres, and "Tritons.” Field observation 
indicates differences in species that recent cabinet lumpers have depreciated, 
though the earlier splitting conchologists had keenly separated them. It is now'
