figures and gives an account of the morphology of a coral and its 

 growth for a period of four months. It carries the development of 

 the coral much farther than any previous work and contains many 

 fundamental results in madreporarian morphology. 



C. H. Eigenmann, Indiana University, Bloomington, Ind. Grant 

 No. 68. For investigating the blind fishes of Cuba. $1,000. 



Abstract of Report. — Dr. Eigenmann did not begin his work under 

 the Carnegie grant until October. He expects to spend from four 

 to .six months in Cuba, during the entire breeding season, and to 

 make general collections in the caves and streams. He will also 

 make an effort to secure the blind fishes from the island of Jamaica. 

 He has made arrangements with the Cuban government to cooper- 

 ate with him, as far as practicable, in giving him facilities for 

 carrying forward his investigation. 



L. O. Howard, Department of Agriculture, Washington, D. C. 

 Grant No. 38. For preparing mamiscript a?id illustratio?is for a 

 monograph on American mosquitoes. $2,000. 



Abstract of Report. — Dr. Howard began his work by making ar- 

 rangements to secure observers at points in the United States, Central 

 America, and the West Indies sufficiently different in their faunistic 

 characteristics to promise comparatively little duplication. He also 

 published an announcement of the proposed monograph for the 

 purpose of attracting volunteer observers and contributors ; and, 

 through correspondence, a great deal has been done in that direc- 

 tion, both in the West Indies and the United States. He also util- 

 ized the services of a number of the members of his force in the 

 Department of Agriculture in making collections and observations. 



He reports that the results as a whole have been surprising to 

 him. A number of new species of mosquitoes have been discovered 

 and one new genus, and much important specific information re- 

 garding the geographic distribution of the different species has been 

 gained. This information has been of special interest and value 

 regarding the yellow fever mosquito (Stegomya fasciata) and the 

 different species of the malaria bearing mosquitoes of the genus 

 Anopheles. A new species of this genus was found in the imme- 

 diate vicinity of Washington. Great advance has been made in 

 following out the life histories of the different species and genera ; 

 this has been done for nearly one hundred species.
