COMPARATIVE ZOOLOGY. 



[Jan. 



REPORT OX THE ALCOHOLIC MOLLUSCA. 



By J. Henry Blake, 



A portion only of my time has been employed in the 

 customary work of this collection ; during the past year it has 

 been concentrated in the basement of the building. 



The Chitons in the collection have been forwarded to Dr. 

 P. P. Carpenter, Montreal, for identification, and with the 

 exception of those kept for a particular purpose, all have been 

 identified and safely returned by him. 



The collection from Mr. Henry Hemphill, mentioned in last 

 year's report, has been identified and distributed. 



There are still unassorted specimens belonging to different 

 collections. They include mainly late invoices, and the 

 collection dredged during the Hassler voyage, all of which 

 are still in the bottles and small boxes in which they arrived 

 at the Museum. 



The collection, however, with the exception of the cases 

 mentioned above, is in a safe condition, and the adopted tem- 

 porary arrangement renders the whole quite accessible. 



Few additions have been made to the collection ; the most 

 valuable being rare specimens from dijfferent parts of Lake 

 Titicaca, South America, dredged by Mr. Alex. Agassiz, 

 assisted by Mr. S. W. Garman ; also by same party specimens 

 from the Pearl Islands, Panama Bay.
