 referred to the following monographs by that author:

Notes are given with only a few species, as the greater part of the 

 material contained in the collection has ialready been discussed in one 

 connection or another, though mostly in brief reports covering special 

 collections or limited faunal regions. The report upon the Echini of 

 the North Pacific Exploring Expedition, by Mr. Agassiz, has been men- 

 tioned above, Subsequentlj'^ Mr. Agassiz examined the entire collec- 

 tion of Echini belonging to the National Museum, in connection with 

 the preparation of his "Eevision of the Echini," in which many refer- 

 ences to this collection will be found. The Blake Echini are described 

 in the second monograph of Mr. Agassiz, above cited. Prof. A. 10. 

 Verrill has described or noticed all the species collected by the U. S. 

 Fish Commission on the Atlantic coast of the United States, north of 

 Cape Hatteras, in numerous papers, each generally covering the explo- 

 rations of a single season. In the following report to the U. S. Fish 

 Commissioner, Professor Verrill has fully discussed the species known 

 from the Southern New England coast up to 1872 : 



Report upon the Invertebrate Animals of Viueyard Sound and Adj;icout Watiis, etc. 

 Report U. S. Comm. Fish and Fisheries, Part I, for 1871 and 1872 (1874), pp. 295-4:8. 



The subsequent notices of Echini by Professor Verrill have mostly 

 appeared in the American Journal of Science since 1872, in the series 

 of papers entitled "Brief Contributions to Zoology from the Museum 

 of Yale College." These have been mainly devoted to preliminary ac- 

 counts of the explorations of the Fish Commission from year to yenr, 

 with brief descriptions of the marine invertebrates. 



The Echini collected by the Fish Commission in the Gulf of Mexico 

 and Caribbean Sea have been noticed by the writer in the last volume 

 of these Proceedings, as follows :
