In view of Hanley's remarks "In the box thus marked in the Linnean Cabinet is still 

 preserved the Lima squamosa of authors (Sow. Thés. Conch, vol. I, Lima, f. i)", there is no 

 reason why the Linnaean name should not be adopted in préférence to the later L. sqitamosa \ 

 this has already been done by several authors, such as Pilsbry, Hedley, Suter, Thiele, and 

 Dautzenberg. The main chfficulty about the identification of this form has been its confusion 

 with species hke L. multicostata Sow., L. caribaea D'Orbigny etc., and to assign to the species 

 an extensive distribution in ail the warmer seas. Lischke (1869) was apparently the first to 

 start the confusion and Dall, Dautzenberg and Fischer and other authors hâve perpetuated 

 and extended the confusion. Unfortunately I hâve not been able to examine suffîcient material 

 of the Mediterranean species and am, therefore, unable to clear up the confusion, but from the 

 material, which I hâve examined, I hâve no doubt that the Mediterranean form is distinct from 

 the Indo-Pacific and the Red Sea species. 



From the collections which I hâve been able to examine, I am of opinion, that the 

 species L. lima is confined to the Indo-Pacific area only and its range does not extend to the 

 Mediterranean or the Atlantic. The number of ribs varies to 25 or even more and thèse often 

 bear several rows of sharp, triangular scales, more particularly in the distal half. The form and 

 size of the scales, however, varies greatly in spécimens from différent localities. 



Distribution : — L. lima is widely distributed in the Indo-Pacific and in the Red Sea.
