GNATHIA SPONGICOLA var. MINOR n. 



The only points of difference between these specimens and the 

 typical form are the smaller size, the smaller and more numerous 

 tubercles on the head, the nearly obsolete lateral swellings of the 

 peraeou segments, the stouter antennae and peraeopods, the absence 

 on the 6th joints of the peraeopods of the fine serrations. 



The oblique ridges on the head bear a row of rather regularly 

 arranged little tubercles or granules. 



These small differences may be ascribed to habitat. The variety 

 lives in burrows in a branching sponge, the branches of which are 

 4-7 mm. in diameter, whereas the typical form inhabits galleries in 

 large massive sponges. 



Each burrow is about 5 mm. long and a little over 1 mm. broad, and 

 is occupied by a <$ and an ovigerous 9 The $ was found either 

 sitting in the mouth of the burrow with the mandibles just projecting 

 or clasping the 9 I n this latter position the hinder part of the $ 

 overlies the anterior part of the 9 . which is clasped by the 3 posterior 

 pairs of peraeopods of the $ .
