spider is quite common among the gardens of Funchal. Two or three 

 species of Mijnapoda are very common, even infesting the houses. 



The freshwater and raai-ine shells liave been pretty thoroughly 

 studied, especially by Mr. Lowe, Mr. Watson, the resident clergyman 

 of the Scotch Church in Funchal, and by the Barone de Paiva, who 

 has recently published a comprehensive treatise on the Mollusca of 

 the Islands of the Madeiran Group. Of the land and fresh water 

 shells Mr. Lowe enumerates one hundred and fifly-five species ; Mr. 

 WoUaston reduces the number of true species to one hundred and 

 thirty-two, of which one hundred and eleven are peculiar to tlie ISIa- 

 deiras; five are common to the Canaries; four to the Azores; one to 

 the Guinea Coast; and eleven to tlie south of Europe. Of the Avhole 

 number, seventy-six species belong to the genus Helix, and twenty- 

 three to the genus Pupa.^ 



The marine shells have been less carefully studied. Mr. Mc Andrews 

 gives a list of one hundred and fifty-six species of marine testaceous 

 mollusca which he obtained whilst dredging for a few days off the 

 coast of ^Madeira. The genera most largely represented are Tellina, 

 Cardhmi, Lucina, Pecten, Ifi/akea, Patella, Trochus, Rlssoa, Murex, 

 Mangelia and Mltra. The boldness of the shore and the nature of 

 the bottom render di-edging somewhat difficult; there are, however, 

 situations where it can be successfully performed, and it is from 

 these few points only that the specimens have been obtained.

1 Of the Madeiran land shells now In the cabinet of the Society, a large number 

 were given to the writer by Mrs. Scott of Is ew York, for some months a resident 

 cf the island. Mr. Watson possesses a beautiful and choice collection of the land 

 and fresh water .shells; and so does also Sr. J. M. Moniz, a Portuguese gentleman 

 in the employ of the Government. Mr. Moniz often has collections of the shells, 

 as well as the ferns and other objects of natural history of the island, for sale.
