﻿BIBLIOGRAPHY 



OF THE 



MEROSTOMATA;* 



WITH AN ACCOUNT OF THE AFFINITIES PROPOUNDED BY THE 



VARIOUS AUTHORS. 



{For references see p. 20.) 



1. 1809. Mr. W. Martin 1 gave a figure and short description of a Limuloid 

 Crustacean from the Coal-measures, which he included with the Trilobita, and named 

 Entomolithus monoculites ? (lunatus). 



2. 1811. Mr. J. C. Parkinson 2 figured a similar fossil from the Coal-measures, 

 Dudley. 



3. 1820. Mr. Charles Konig 3 figured a Coal-measure Limulus, naming it Beli- 

 nurus bellulus, but there is no description accompanying it. 



4. We find the first notice of the discovery of Eurypterus in America (in 1825), by 

 Dr. J. E. Dekay, 4 who described and figured the only species then known {Eurypterus 

 remipes), and referred it to the class Crustacea, and to the order Branchiopoda. 



5. The remains of an English species of Eurypterus (probably two feet in length) 

 were described in 1831 by Dr. J. Scouler, 5 of Glasgow, under the generic name of 

 Eidothea. 



6. Dr. Richard Harlan 6 published the description of a second American species 

 in 1835 {E. lacustris). 



7. Prof. Milne-Edwards, 7 in 1834-36, observes, with respect to the genus Eurypterus, 

 established by Dekay, " They have externally many points of resemblance to Pontia and 

 Cyclops, and they also seem to indicate, in some respects, a passage between these 

 animals and the Isopoda. The body is broad and more or less pyriform, and the head 

 very distinct from the thorax, which is divided into many segments, but is not separated 

 by any marked distinction from the abdomen. The head bears on its superior surface two 

 reniform eyes, well developed, and distant from each other. Two pairs of antennae have 

 also been distinguished ; and whatever other appendages there may be, appertain to the 

 mouth. Lastly, on each side of the first thoracic ring one sees a great lamelliform 

 swimming- foot, with a rounded termination." 



" Geologists," M. Milne-Edwards adds, " describe three species of Eurypterus, viz., 

 E. remipes, Dekay, E. lacustris, Harlan, and E. Scouleri, Hibbert." 



* Should any omissions be discovered in this history, I shall feel obliged to palaeontologists who will 

 call my attention to them, that they may be inserted in the future parts of this Monograph. — H. W.
