1871.] SENATE- No. 327. 13 



3,600 specimens of them, belonging to 170 different species and 

 assorted in 610 glass jars, are catalogued, labelled and placed 

 by myself in the exhibition room ; the rest may be labelled in 

 the course of two or three months. 



Among the new species of marine fishes of Brazil 1 found 

 two of the genus Thalassophryne, two of the genus Uranosco- 

 pus, two of the family of Scisenidas (Pachypops and Micropo- 

 gon), one of the genus Centropomus, etc., etc. Among the 

 species already described are fine and beautiful specimens of 

 Gobioides Broussonetii C. Val., from Rio Para ; Corniger spino- 

 sus Agass., from Rio Janeiro; Pachiurus Lundii Reinh, from 

 Rio das Velhas ; Belone taeniata Gthr, from Gurupa, etc. ; Bor- 

 ridia grossidens from Rio de Janeiro. In regard to the geo- 

 graphical distribution of the fishes, Prof. Agassiz's Brazilian 

 collection is without doubt the most important in the history of 

 Ichthyology. 



Besides the above I have completely examined Mr. Garett's 

 most valuable collections from the Society, Kingsmill and 

 Sandwich Islands. They contain more than 250 species, in 

 nearly 2,400 specimens, and are in the best state of preserva- 

 tion. I hope to be able to arrange and catalogue this collec- 

 tion also during the next year, and to publish a scientific cata- 

 logue with descriptions of the new species. Among the fishes 

 of the Sandwich Islands I will only mention a beautiful speci- 

 men of Pogonoperca ocellata Gthr. 



Finally I have begun the scientific revision and determina- 

 tion of the Holocentridas and Percidae for the systematic 

 collection. — Nothing has been done during the present year to 

 increase the collection of Reptiles, which is, however, in a 

 satisfactory state of preservation. 



Report on Conchology, by John G. Anthony. 



In my last report made December 31st, 1869, it was promised 

 that during the current year some progress should be made in 

 mounting, arranging and identifying our Marine Shells, and 

 that the present statement would show a marked improvement 

 in that respect. 



Syice then 2,417 tablets have been added, mounted with
