Larger hand longer than the carapax and shaped much as in A. stren- 

 uus Dana, but more elongate. Both margins are constricted and a 

 well marked longitudinal sulcus runs backward on the lower margin. 

 The inner and outer surfaces of the hand are sulcate. The fingers are 

 nearly as long as the palm, the dactylus being slightly longer than the 

 pollex. The carpus of the second pair is five jointed; first joint as 

 long as the next two, second as long as the third and fourth, which 

 are equal and together are as long as the fifth. The hand is about as 

 long as the fourth and fifth carpal joints together.

 In this species the constriction on the lower margin of the palm is 

 very slight and possibly it should be placed near ^. lottinii (infra), 

 but it appears, however, to be more closely allied to Alpheus sulcatus 

 than to any other form. The types are in the collection of Union Col- 

 lege and were brought from Key West, Fla., by Prof. H. E. Webster, 

 to whom the species is dedicated.
