120 REPORTS ON INVESTIGATIONS AND PROJECTS. 



of the opportunity for further study afforded by the varied echinoderm 

 fauna of Montego Bay, and he made a large collection of such species as 

 Centrechinus (Diadema), Toxopneustes (Lytechinus) , Hipponoe, and Ci- 

 daris in order that he may study their variations. In relation to Tennent's 

 work, it is interesting to state that Professor Jackson found living adult 

 echini upon the Montego Bay reefs which appear to be hybrids between the 

 common species Hipponoe and Toxopneustes. This leads us to hope that, 

 given suitable conditions, it may be possible for Professor Tennent to rear 

 his hybrids to maturity. 



Among other studies carried on at Montego Bay, mention should be made 

 of those of Dr. Joseph A. Cushman, who investigated the living Foraminif- 

 era of the shallow waters, and also the fossil forms of the elevated lime- 

 stones of Jamaica. His studies indicate that a series of dredgings should 

 be carried out in order to determine the bathymetrical range of the several 

 living species, and thus possibly determine the depths beneath the sea from 

 which the limestones of Jamaica have been raised. 



Prof. Gilman A. Drew continued his well-known studies of the sper- 

 matophores of cephalopods which he has been conducting for some years 

 past at Woods Hole. Abundant Octopus material was obtained from the 

 fishermen at Montego Bay, and indeed the local fishermen were of great aid 

 to us in bringing in many specimens which we ourselves would have found 

 it difficult to obtain. 



Prof. H. E. Jordan found that it was impossible to study the maturation 

 and early developmental stages of the eggs of Bchinaster crassispina, for 

 these star-fishes were not yet ripe, and he therefore investigated the sperma- 

 togenesis of the mongoose. Mr. E. E. Reinke acted as general assistant in 

 the management of the laboratory and continued his interesting work upon 

 the two sorts of sperm-cells found in many marine mollusks. 



Finally, I can not close this brief account of our work at Montego Bay 

 without alluding to the extraordinary efficiency and energy in our interest 

 displayed by Mr. George M. Gray, curator of the Woods Hole Laboratory, 

 who accompanied the expedition as collector. Mr. Gray is a veteran in this 

 field and he fully succeeded, due to his untiring zeal and to his intimate 

 knowledge of the habits and haunts of marine animals, in providing each 

 and every one of us with all the material we required. 



To His Excellency the Right Honorable James Bryce, British Ambassador 

 to America, we are indebted for letters to their excellencies the governors 

 of Jamaica and of the Bahamas. In response to these credentials, His Ex- 

 cellency Sir Sydney Olivier, K. C. M. G., governor of Jamaica, was so kind 

 as to permit us to import our scientific apparatus free of customs duties, and 

 he displayed toward us other appreciated acts of courtesy, in these being 

 joined by the Honorable W. Coke Kerr, esq., Custos of St. James. 



To Henry M. Doubleday, esq., American consul at Montego Bay, and to 

 Mrs. Doubleday, it is a pleasure to express our appreciation of their cordial
