994 REVISION OF THE AUSTRALIAN L.EMODIPODA, 



aiticuli. Propodos of posterior gnathopoda in the male with a 

 rounded process over the articulation of the dactylos ; palm defined 

 by a bifid denticle. 



Female. — The head of this species is without spines, about 

 equal in length to the following segment. The second, third, and 

 fourth segments are nearly equal ; the fifth and sixth are nearly 

 equal in length, longer than the preceding three ; the last segment 

 is about half the length of the fifth. The superior antennae are 

 as long as the head and following three segments ; the first and 

 second segments of the peduncle are stout, the second the longer 

 and somewhat narrower at the base than towards the extremity ; 

 the third segment is rather more than half the length of the 

 second, narrower, being broadest towards the distal end ; the 

 flagellum is a little longer than the peduncle, with twenty articuli, 

 of which the last is extremely small. The inferior antennae are 

 about two-thirds of the length of the superior pair, the second and 

 third joints of the peduncle small, the fourth and fifth nearly 

 equal, each nearly three times as long as the third ; the flagellum is 

 once and a half the length of the last segment of the peduncle and is 

 composed of nine joints 



The propodos of the anterior gnathopoda is triangular in lateral 

 outline; the palm is very slightly convex, defined by a short tubercle 

 and ornamented with short hairs. The posterior gnathoj)oda are 

 as long as the superior antennfe (gths of an inch) ; the propodos is 

 /„th of an inch in length, and nearly ^rd of that in breadth, of a 

 long oval shape in transverse outline, the upper (dorsal) border is 

 slightly angulated near the middle, but nearer the proximal 

 than the distal end ; the lower (ventral) border has a well-defined 

 palm which is slightly convex and is defined by two small 

 tubercles, or more correctly, by one bifid tubercle, and has five 

 serrations towards its distal end with a row of short setee ; the 

 • dactylos is more than half the length of the propodos, geniculate 

 at the junction of its proximal with its middle third. The first 

 and second })ereiopoda are slender, but as long as the others, (as 

 long as the head and the two following segments — .jj^ths of an inch), 

 ■with long narrow branchire. The two posterior pairs are short
