The abdomen is abruptly narrower than the thorax, the first segment being only 3mm. wide and deeply immersed in the last segment of the thorax. The second seg-ment is wider, being mm. in width, and the three following are nearly as first five segments are subequal in length and are each about as long as the sevenththoracic segment, mm. The sixth or terminal segment is 4 mm. wide at the baseand tapers a little to the extremity, which is 3 mm. wide. This segment is Seventh leg. X15}£Fig. 19.—Meinertia guttata.

The posterior extremity is slightly excavate in the middle. The uropoda donot reach the extremity of the last abdominal segment; both branches are narrow andshort, the inner slightly shorter than the outer. The legs are all prehensile; there is a carina on the basis of the last four pairs whichgradually increases in height; the ischium of these legs is also produced on the innermargin in a wide process. About 7 specimens of this species, all females, were collected at Jolo, ships side, byelectric light. This species differs from Meinertia trigonocephala (Leach) a and Meinertia oxyrrhyn-chsena (Koelbel)& in the shape of the terminal abdominal segment, the length of theuropoda, the shap
