58 MISS MAY E. BAINBEIDGE ON 



General Appearance (female). 



The genital segment and cephalothorax are much flattened and are invested hy a 

 loose hag-like memhrane. The first maxillipeds (fig. 38, Mxp}) are rather more than 

 one-third of the length of the cephalothorax. They appear to he quite distinct, but the 

 investing memhrane seems to be fused along the median line, so that the two appendages 

 cannot be separated. The ends are enlarged into two semicircular folds, between which 

 the tenaculum lies. In the genital segment on either side are two large thick -walled 

 cement-glands (CO.). The relations of the genital apparatus were not easy to make out 

 in preserved specimens, but the following points may be noticed : — The ends of the ovi- 

 ducts have thick chitinous walls ( Od.) ; they open on the raised knobs on either side of the 

 minute abdomen (G.O.). Two boat-shaped structures with chitinous walls lie at right 

 angles and dorsally to them, and are probably the recejptaculum seminis (M.S.). At the 

 inner side of the thick wall of the oviduct is a smaller chitinous structure (x), lying 

 apparently dorsal to the receptaculum seminis. Vejdowski *,in his paper on Tracheliastes 

 folycolpus, Nordm., figures structures not unlike these, but the canals which he observed 

 leading from either end of the receptaculum seminis to the external opening were not 

 made out in Anclwrella stellata. 



On the abdomen are two minute chitinous structures ; these are probably the external 

 openings of ducts leading into the receptacula seminis. 



The appendages are very similar to those of Anclwrella uncinata, Miiller. 



The Mandible (fig. 42). — This is very irregularly toothed. The first tooth is large, 

 followed by two smaller teeth, the fourth is very long and prominent, the fifth and sixth 

 are smaller. Following these is a curved cutting-edge. There are six teeth in all. 



In size these specimens corresponded very closely with those obtained on the 

 Hake by T. Scott.
