Length, one-tenth of an inch. The head is transverse, and nearly 

 a rectangular segment, with the eyes near the anterior angles ; the 

 following segment is somewhat ovate, wider behind ; the next three 

 are short, but very gradually increasing. The caudal stylets are a 

 little hairy. The superior antennae have the second joint about as 

 long as third and fourth together. The inferior antennae are slender, 

 and shorter than the first two basal joints of the inner antennae. The 

 anterior legs excluding the hand are nearly as long as the superior 

 antennae. The fingers are very slender, and widely separated when 

 their apices are in contact. There are one or two setae on the finger 

 near apex. Abdominal legs five pairs. 



This species is Caprelloid in habit. It was observed by the author 

 attached by its hinder legs to sea-weed, and reaching out the long 

 arms in different directions, as if in search of prey.
