16 MUSEUM OF COMPARATIVE ZOOLOGY. [May, 



Several special and faunal collections have also been sent us, 

 and deserve particular mention. 



From Mr. Henry Dohrn we have two packages, with 130 

 species, mostly collected by him at the Cape de Yerde Islands 

 and on the African coast. Mr. McAndrew sends us 234 species, 

 a large portion of which were dredged by him in the Gulf of 

 Suez, and which, therefore, are particularly valuable for faunal 

 considerations. 



Another and very important addition to our faunal collec- 

 tions has been received from Dr. Cox, who sends us two 

 packages containing a series of terrestrial and marine species 

 from a region hitherto very indifferently represented in our 

 collection, and the beauty and perfection of the specimens, in 

 addition to their rarity, render them doubly valuable, and call 

 for our warmest and most hearty thanks. 



From J. W. Sever, Esq., of Boston, we received early in the 

 year two packages comprising 177 species, 529 specimens of 

 East India marine shells, which for beauty and perfection could 

 not well be surpassed, and leave us but little to be desired from 

 that faunal region. 



Since our last report we have sent to our correspondents, 27 

 in number, 33 packages, containing 3,151 species and 10,655 

 specimens. This leaves us in debt to but three persons for ex- 

 changes, while we are largely in advance to others, so that this 

 portion of the work of the Museum may be said to be in a very 

 satisfactory condition.
