294 PHOCKKDINGS OF TnE MALACOLOGICAL SOCIETV. 



Stro7nbiformes. PI. iii, fig. 9. These Snails liave a perfect round 

 moutli, well defined or bordered, by which particular alone they are 

 immediately distinguished from the Strombi, whose length and 

 slenderness they emulate ; for the mouths of the Strombi are long, 

 and have a very thick columella aside them, erect, and somewhat 

 twirled; and many kinds besides prolong into a wry gutter, turning 

 backwards, like the mouth of a Soal, or other flat-fish." This shows 

 ray earlier conclusion needs emendation, as Costa did make up his 

 word from Sirombus, a shell, and formis, but his Strumhus is not the 

 commonly accepted one, but is wliat we call Cerithimn. On p. 212 

 he defines his Strombi, and figures a specimen on pi. iv, fig. 7. 

 Oo-sta's figures are really splendid, and his typical Stromhus I would . 

 identify as the Australian shell called Clava herculea^ Martyn. 



Tpkricula, Herrmann. 



In Sherborn's inestimable Index Animalium, 1902, p. 1007, appears 

 " Turricula J. Herrmann, Tab. aif. Anim. ed. 2, 1783, tabula. — G ". 

 Such an entry demanded investigation, as this is the earliest use of the 

 genus-name Turricula^ and apparently it was proposed for a Gastropod 

 mollusc. I therefore looked up the reference, and would put on 

 record my conclusions for the benefit of those unable to personally 

 verify such matters. 



On the tabula quoted a scheme is given purporting to show the 

 connexions between the varied mollnscan families, genera, and 

 species. No explanation is given, so that the table mnst be studied 

 alone. The species names are in italics, the group names in roman. 

 "Turriculae" thus appears, and against it ^\.y,\\i\f, Buccinum suhulatum in 

 italics. This suggests at first sight that B. suhulatuvi was an example 

 of Turricula. Such a conclusion would mean the substitution of 

 Turricula for T'erebra, which is of later date. I would here digress 

 and point out that Terebra is commonly ascribed to Bruguiere, 1789. 

 In the Encycl. Method. Vers, vol. i, p. xv, 1789, where this name is 

 introduced by Bruguiere, only a short diagnosis is given, and no 

 species cited. I consider these diagnoses quite indeterminable, and 

 practically nomina tmda, and would, therefore, recognize Terebra as of 

 Lamarck, 1799, where in the Mem. Soc. Hist. jSTat. Paris, p. 71, 

 a diagnosis is given, and accompanied bj' the species Buccimnn 

 subulafum, L. To revert to Turricula). Examination of Herrmann's 

 tabula dispels the conclusion tliat this was intended as a generic name 

 for B. subnlatum, and suggests rather that it was more ])robably the 

 group name of a Stromb affinity, which Herrmann considered passed 

 into B. subulatum. For preceding it is named Strombi digitati, and 

 later on is noted Cypraea and Conus, then " C. ventricosi ", followed 

 by " Vol. cylindroideae ". This will suggest the confused and 

 unintelligible state of the tabula, which is emphasized by the following 

 extract: '•'' Buccinum is opposed by B. harpa, and connected by a long 

 line with * Buccin. Cassidea\ against which stands '■Ner. elegans, M,', 

 while a continuation of the line ends in 'Buccina ampullacea\'^ To me 

 the ''Ner. elegans, M." has nothing to do with " Bucein. Cassidea''\ 

 but is relative to Turbo, which can be seen a long way above.
