claw. On the external side of the dactylus there is a thin blade or 

 flange which runs the whole length of the segment and is some- 

 what reflected outwards ; from certain points of view the dactylus 

 thus appears very broad. 



The last three peraeopods are comparatively stout ; the third 

 reach beyond the scale by about twice the length of the dactylus. 

 The merus is about 9 times as long as broad. The propodus 

 (text-fig. 18c) bears some setae and a few fine spinules on its poste- 

 rior border and is from about 6*5 to 7 times as long as the 

 dactylus. The latter segment (text -fig. 18^) is rather broad and 

 the accessory tooth is small. 



The sixth abdominal somite is half as long again as the fifth. 

 The foremost of the two pairs of spinules on the upper surface of 

 the telson is placed a little in front of the middle of the telson- 

 length, the second midway between it and the apex. 



The largest specimen, an ovigerous female, is about 16 mm. 

 in length.
