joint not being seen. Joint (2) is broadly rounded, joint (3) is narrower and more 

 elongated ; joint (4) is hollowed out to receive joint (5) which is larger but similar 

 in form to (4) and also to joint (G) which is, however, the smallest of the three 

 joints 4, 5, and 6 have each their distal borders sharply pointed. The 7th and 

 terminal joint is a simple claw, not chelate. The total length of this entire 

 appendage is 2 inches. 



Having instituted a most careful comparison of the fossil with the somites 

 and appendages of various recent forms, I am led to refer it to the order 

 Amphipoda — Normalia and to the division Oammaridce among some of the 

 natatorial forms of which occur limbs not unlike the fossil lief ore us. I therefore 

 propose to name it JVccrogammarus* Sahoeyi, after its discoverer.* 



Although it may seem rash to refer such very fragmentary remains as this 

 and the preceding one to any special Crustacean family, yet I venture to believe 

 that the very fact of my describing the one and recalling attention to the other 

 may lead to the prosecution of fresh investigations, by the Blembers of the Club, 

 of the beds in which they occur and thus to the discovery of further evidence 

 which may more fully elucidate these remarkable forms. 



* From viKpug dead, and proper name.
