TOR NAT ELLA 



Plate I. 



Genus TOENATELLA, Lamarck. 



Teda cylindraceo-ovata, pU'ru)U(]uf iransversiin Uneari-siii- 

 cuta, spird parvd, aperlurd oblonr/d, columella ad basin 

 valide contorto-plicatd, iuterdnm plica secundd plus 

 miuits obsoletd. 



Shell cylindrically ovate, generally transversely linearly 

 grooved, spire small, aperture oblong, columella 

 strongly twistedly plaited at the base, with sometimes 

 a second plait, which is more or less obsolete. 



The genus Tornatella comprises a few characteristic 

 species, distinguished by a cylindrically ovate short-spired 

 form of shell, having a remarkably strongly-developed 

 twisted plait at the base, which, unlike that of the great 

 majority of gasteropodous mollusks, is not emarginated or 

 channelled. For the sake of convenience, a few small 

 species are added, constituting the genus Leucotina of 

 Adams, in which the spire is more acuminately turbinated, 

 and the columellar plait only very faintly developed. All, 

 with one or two rather conspicuous exceptions, are trans- 

 versely linearly grooved, and in most species the grooves 

 are finely punctured throughout. The typical species of 

 Tornatella are all inhabitants of the Eastern Seas, and we 

 have a fine one, T. tornatilis, ranging throughout the 

 seas of Europe. Of the Leucotina species one is from the 

 China Seas, one from Hongkong, and one from the Bay 

 of New York. 



Species 1. (Fig. a, b, c, JMus. Cuming.) 



Tornatella coccinata. Tom. testa cyUndraceo-ovatd,

 punciis cocciueis out caridescentibus profuse aspersd, 

 apice acuto, coluiiielld hlplicald, saperiore subobsciirn,

The scarlet Tornatella. Shell cylindrically ovate, 

 rather stout, transversely ])unctured-grooved through- 

 out, white, profusely sprinkled with scarlet or bluish 

 dots, apex sharp, columella two-plaited, the upper 

 rather obscure, the lower very prominent, duplicate.

Ilab. Cagayan, Province of Misamis, Island of Mindanao, 

 Philippines (dredged from sandy mud, at the depth of 

 tvventy-five fathoms) ; Cuming. Singapore ; Cuming. 



This very characteristic species is of a peculiarly swollen 

 cylindrical form. The typical scarlet-coloured variety is 

 from the Philippine Islands, the dark leaden-blne variety 

 from Singapore. 



Species 2. (Fig. a, b, Mus. Cuming.) 



Tornatella flamjiea. Torn, testa obeso-omtd, trans- 

 versim widique dense punctato-sulcatd, alba, macnlis 

 crescentiformibus ant Jlammis rvfescentibus striyatd, 

 spird breviusculd, columelld valide imiplicatd. 



The flamed Tornatella. Shell stoutly ovate, closely 

 densely punctured-grooved throughout, white, streaked 

 with reddish flames, or crescent-shaped spots, spire 

 rather short, columella strongly one-plaited.

Ilah. Java. Island of Ticao, and Correjidor, Philippines 

 (dredged at a depth of about seven fathoms) ; Cu- 

 ming. 



The markings of this beautiful species consist normally 

 of somewhat square crescent-shaped blotches, which in 

 varieties run into one another and form confused longitu- 

 dinal streaks. 



Species 3. (Fig. a, b, Mus. Cuming.) 



Tornatella soliddla. Torn, tesld oblongo-ovatd, sub- 

 ci/ltudraced, transoersim undlque dense punctato-sul- 

 catd, alba, maculis parcis qniidratis cternleo-niijrican- 

 tibus profuse irregulariter aspersd, spird plus minus 

 couico-elevatd, cohauelld valide uniplicatd. 



The solid Tornatella. Shell oblong-ovate, some- 

 what cylintb'ical, transversely densely punctured- 

 grooved throughout, white, profusely irregularly 

 sprinkled with small square, bine-black spots, spire 

 more or less conically raised, columella strongly one- 

 plaited.
