The. Zoology of the Sandwich Islands. — Fourth Report of the 

 Committee, consisting of Professor A. Newton ( Chairman), Dr. 

 W. T. Blanford, Dr.' S. J. Hickson, Professor C. V. Riley, Mr. 

 (). Salvin, Dr. P. L. Sclater, Mr. E. A. Smith, and Mr. D. 

 Sharp (Secretary). 



The Committee were reappointed to continue their report on the 

 present state of our knowledge of the zoology of the Sandwich Islands 

 and to take steps to investigate ascertained deficiencies in the fauna, 

 with power to co-operate with the committee appointed for the purpose 

 by the Royal Society, and to avail themselves of such assistance as may 

 be ofi'ered by the Hawaiian Government. 



During the past year your Committee have been harmoniously co- 

 operating with that appointed by the Royal Society, and Mr. Perkins's 

 labours in the islands have been satisfactorily continued. Since your Com- 

 mittee last reported Mr. Perkins has been diligently exploring in succession 

 Molokai, Lanai, and Maui, from the first two of which very considerable 

 collections in almost all branches of the terrestrial fauna have already 

 been received, while one is shortly expected from the third. By the last 

 accounts he was about to proceed to Kauai. 



Although far from having completed the zoological exploration of the 

 archipelago, the Committee have thought it best that Mr. Perkins should 

 return home in the course of the autumn, and have instructed him accord- 

 ingly. They hope to obtain his assistance, in conjunction with that of 

 other competent zoologists, towards working out his extensive collections, 

 the value of which it is difficult to over-estimate, since evidence of the 

 growing scarcity of many, and of the extinction of not a few members of 

 the endemic fauna becomes stronger the more the subject is investigated. 



In view of making arrangements necessary for this purpose your Com- 

 mittee request that they may be reappointed, with the same powers as before, 

 but they do not ask on the present occasion for any grant of money.
