short, but the figures of the two species show that the relative 

 proportions are the same in both. The telson in the present 

 species has each apex divided with a simple outer tooth and a 

 slightly shorter inner bifid one, a setule separating them. Mr. 

 Walker's serraticriLs has the apices differently arranged. Length, 

 from head to end of telson, about 3 mm.

Family AORID^.

To the seven genera defined in " Das Tierreich " as belonging 

 to this family. Dr. Norman in 1905 added Corema2nis for the 

 species previously known as Microdeutopus versiculatus (Bate). 

 On the other hand, investigation of the " Thetis " Amphipoda has 

 led to the transfer of the genus Dryopoides to the Corophiidse, 

 but M. Chevreux, by an opportunity of examining the mouth- 

 organs in a new species of Xenocheira, finds that that genus ought 

 to be transferred from the Photidae to the Aoridse. The new 

 genus Paraoroides is exceptional in this family by having the 

 third uropods one-branched.

Nine species of this genus are described in "Das Tierreich," to 

 which the appendix adds mention of L. smithi, Holmes, 1903, 

 L. podoceroides, Walker, 1904, and L. chelattis, Walker, of the 

 same date. To these must be added L. leptocheirus, Walker, 1909, 

 from Wasin and Suez, a species in which the second gnathopod 

 of the male closely resembles that of Coremapus versiculatus, 

 while the first gnathopods are quite distinct.
