Ft-cslitcater Crustacean from Para. 297 



tlic two branches of the outer na<>;elhiin of the antennules are 

 divided to the base may, however, be taken as indicating for 

 tlio ^^enus a place within the PaUemonidte. The other genera 

 usually included in this family which have no palps on the 

 mandibles are Fahvinoticfes, Heller, Faheinoiwpsis*, Borra- 

 dailoj and Ancijlocaris^ Sclienkel. From these the present 

 genus is distinguished by the form of liie rostrum and by the 

 absence of spines except the antennai on the antero-lateral 

 region of the carapace. 



Euryrhynchus Wrzesniowslcii, ]\Iiers. (Fig. 1.) 



Euri/rhipichis Wrzesnmvskii, Miers, Proc. Zool. Soc. 1877, p. GG2, 

 pi. Ixvii. ti-3. 2-2 6. 



Merus of second peraeopods with two inconspicuous rounded 

 lobes at the distal end below ; carpus without a spine on the 

 inner side ; fingers hardly longer than the palm. Telson 

 with the tip rather narrowly rounded, projecting nearly as 

 far as the lon;r lateral si)ines.

Ewyrhynchns Wrzesniowshii, Miers. Distal end of telson. 



I can find no trace of the '' small spine between the eyes 

 and the rostrum " described by Miers, and the telson, as 

 figured, is much too narrow.

Euryrhynclius Burchelli, sp. n. (Figs. 2-8.) 



Merus of second perseopods with two acute spiniform teeth 

 at the distal end of its lower surface ; carpus with a sharp 

 tooth on the inner side near the distal end ; fingers distinctly 

 longer than the palm. Telson with the tip broadly rounded, 

 not projecting nearly as far as the long lateral spines.

• Mr. Borrndaile has poiuted out to me that this name was first usod 

 by Stiu)psou in 1871 (Ann. Lye. Nat. llist. New York, x. p. 1-8), but 

 apparently only as a nomen nudum. Whether Borradaile'a later use of 

 the name is illejjal may be left to the decision of those interested in such 

 questions.
