CATALOGITE OF MAKTNE SPONGES, COLLECTED BY MR. JOS. WILLCOX, 

 ON THE WEST COAST OF FLORIDA. 



BY HENRY J. CARTER, F. R. S., ETC. 



The fragments of the sponges collected by Mr. Willcox which 

 reached me from Philadelphia on June 12, 1884, are all numbered, 

 1-59, and have been taken from specimens which, bearing the 

 same numbers, have been retained at Philadelphia for identifica- 

 tion, when the result of my examination shall have been received ; 

 hence the numbers in the catalogue will be found to correspond 

 with those on the specimens at Philadelphia, 



It should be remembered that they are all dry specimens, and 

 that what I have to examine are only " fragments," hence there 

 is very little to be said of each beyond name, form, consistence 

 and color, together with the form and dimension of the spicule 

 respectively, while they are arranged in accordance with the class- 

 ification that I have proposed in ray " Notes Introductory to the 

 Study and Classification of the Spongida," published in the 

 Annals and Magazine of Natural History, for 1875, vol xvi, 

 p. 1, etc.^
