Along with Mysis relida, Loven, Pmitoporeia affinis, Lindstrcim, " was found at every haul from 

 the shallowest to the deepest." Cranrjonyx gracilis. Smith, n. s., was also taken, and is 

 here described, with the remark that " the incubatory lameUte of the female are very large, 

 projecting much beyond the coxae of the anterior legs, as in C. remrvutus, Gruhe, which 

 our species much resembles in the form of the antennulse, antennae, gnathopoda, etc., while 

 it difEers much in the ultimate pleopoda and in the form of the telson." Garnmarus 

 lacustris, Smith, n. s., length 15 to 20 mm., is also here described. It was afterwards 

 named Garnmarus limnxios.

1871. Woodward, Henry, born November 24, 1832 (H. W.). 



On Necrogammarus Salweyi (H. Woodward) an Amphipodous Crustacean from 

 the Lower Ludlow of Leintwardine. (February 23, 1871.) Transactions of the 

 Woolhope Naturalists' Field Club. 1870. Hereford, mdccclxxi. pp. 271, 272, 

 and Plate. 



It is explained that the Crustacean fragment, on which this new genus and species were founded 

 " was noticed and figured in Messrs. Huxley and Salter's important work on the Eurypteridje 

 (Memoirs of the Geological Survey, Monograph I., 1859, p. 25, pi. XIIL, Fig. 7). Professor 

 Huxley observes, ' The fossil figured is evidently Crustacean, but it exhibits no character by 

 which it can be identified as a part of a Pter-ygotus.' (See Fossil Sketches, No. 11, Fig. 2)." 



" It presents us with the side-view or profile, of what appear to be three laterally-compressed and 

 thin-crusted somites or body-rings." The feet "are articulated along the border "of the 

 somites. From the dorsal line to the border these somites are said to measure between 1| 

 and 2\ inches, while from front to back they measure 10 or 11 lines. 



"The third segment (c) is 10 lines broad and measures 2 inches from the dorsal line to the 

 sharply-pointed epimeral border ; from the posterior side of this the limb (c .3) is given off 

 of which six joints are visible, the first or basal 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 (6) 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."
