Hab. — Mediterranean Sea. 



Description. — "Coquille a peu pres semblable a celle de T. navalis inais 

 plu3 petite, a peu pres aussi liaute que large ; oreillette anterieure portant. 

 plus de soixante stries ; oreillette postcrieure moins abaissee que chez le T. 

 navalis. 



" Palettes courtes, ressemblant a un petit 6pi d'orge formees de buit a dix 

 godets courts, comprimcs, irubriques, denticules a leur bord inferieur et le plus 

 souvent noiratres. Epines latcrales peu developpces. Ptidicule cylindrique, 

 grele, blanc, un peu plus long que la palette. 



" Observ. — Cette charmant espoce n'attient jamais de grandes dimensions, 

 mais ses ravages n'en sont pas moins redoutables; car elle abonde dans les 

 lieux ou elle vit." — Fischer, desc. of T. Philippii. 



Fischer separates Philippii from minima, and remarks that the latter is 

 described from a young shell. Jeffreys unites the two, giving the preference 

 to Blainville's name, as the oldest which is not pre-occupied.

" Coquille extn'mement petite, a peu pres aussi haute que large; oreillette 

 et zone anterieures plus grandes queles posterieures ; stries trcs nombreuses, 

 presque egalement, serrees et espacees sur les deux cotes de l'angle anterieur. 



" Palettes portees sur un tres-long pedicule et formees de douze articula- 

 tions en godets, non epineuses sur les cotes." — Fischer.

 Hab. — East Indies. 



Description. — The valves and tubes of this species are unknown, and but 

 two specimens of the pallets exist in European collections ; from one of these 

 pallets (that in the Jardin des Plantes) Lamarck's description is taken,* which 

 in fulness of detail and accuracy is scarcely inferior to the description of T. 

 navalis, by Linnseus. 



The palletB are quite large, the blade composed of twenty or more triangu- 

 lar joints, which are attenuated laterally into sharp projecting points. The 

 stalks are somewhat shorter than the pallets, moderately thick, rounded, and 

 about one-third the width of the blade. Total length about one inch. 



Mr. Jeffreys remarks that they are "allied, to the pallets of T. b i p e n n a t a, 

 although evidently distinct." 



This species is not the T. palmulata of Forbes and Hanley, nor of 

 Philippi.
