298 STALK-EYED CRUSTACEA 



strongly ciliated. The other legs have a line of granules 

 placed upon the anterior face of their fourth joint.

Carapace usually more or less membranaceous, convex 

 or depressed, with the antero-lateral margins entire or 

 but very slightly dentate ; front, orbits, and eye-peduncles 

 very small. The buccal cavity is usually arcuate an- 

 teriorly. The fourth, and usually the third, joint of the 

 external maxillipedes is well developed, and the fifth 

 joint articulates with it at the summit or at the antero- 

 internal angle, or, more rarely, at the antero- external 

 angle. The first pair of legs, in the adult male, is small 

 or moderately developed. Walking legs are slender and 

 usually naked; terminal joint styliform, unarmed. The 

 abdomen of the male does not cover the sternum between 

 the base of the last pair of legs. 



Individuals of this family may be found in the West 

 Indian Sea; they are very small, and usually live in shells 

 along with their legitimate tenant, so may be easily over- 

 looked. It is on this account that I give a definition 

 of the family and of the various subfamilies as given by 

 Mr. Miers in the Challenger Reports.
