it necessary, tliat I should go on mentioning all tlie nu- 

 ruerous variations existing iu the MSS. 



9. Fiually, from tho Memoranda of Mr. Marao I have 

 selected many loose papers, which I have bound up together 

 in this bundle. They contain many original and interest- 

 ing observations on the habits, localities, etc, of many of 

 our Mollusca, which, according to my humble opinion, 

 deserve to ba taken care of. I beg to read a few of these 

 observations, so that the Society may judge of their 

 merit. 



10. This is, Mr. President and Gentleraen, the amount 

 of inforraation which I can offer you with refcrence to the 

 MSS. and colloction of shells of the late Mr. Mamo. 



I beg to conclude this Report by observing that the 

 Fauna of the Gaulo-Maltese Mollusca is a natural subdivi- 

 sion of the Mediterranean Fauna, so well known by the 

 investigatious of Poli, Verany, Milne Edwards, Delle Chiaje, 

 Philippi, Professor Forhes, and Deshayes, and more espe- 

 cially of that of Sicily, so well figured and described by 

 Professors Benoit, Aradas, Maravigna, and others. 



Ou referring to the " Fauna Molluscorum Regui utriusque* 

 Sicilia?, " we flnJ that Philippi has reckoned about 619 Ma. 

 rine Mollusca simply on the coast of Sicilv, whilst in Mr- 

 Mamo's Cataloguo of Maltese Mollusca we find about 364. 



Four years ago a fine specimen of Pauopaea aldro- 

 vandi, Meu, was brought to me at the University by some 

 Maltese fishermen, taken in the neighbourhood of the Island, 

 which is not in Mr. Mamo's Catalogue. I am strongly 

 ^mpressed tvith the opinion that on closer researches, espe- 

 cially by dredging, mauy new species might bo added to 

 the Fauna Gaulo-Melivetana, which will give stronger evi- 

 dence to the fact, that 4< while iu its western part, the Me- 

 diterranean Fauna is identical with that of the adjacent 

 Lusitanian coast, and the number of speeies diminishes 

 eastward, it is, however, enriched by a considcrable number 

 of new forms, as yet only known in this part of the Me- 

 diterrancan Fauna" (Woodward). Such additions will per- 

 haps prove many more accessions than those hitherto known
