o, 35 mm. thick, and a trifle longer than the visible part, long 0,75 mm., of basal article; 

 3 ld article 0,5 mm. long, 5 / e of 2 nd . Stylocerite as long as basal article. Antennal peduncle as 

 long as that of the upper antennae, terminal spine of the scaphocerite reaching almost to the 

 tip of the antennular peduncle. 



The peraeopods of the i st pair are wanting. Of the right leg of the 2 nd pair the merus 

 is 9,5-times, of the left 9-times as long as wide. The carpal segments of the right leg are 

 1 mm., 0,48 mm., 0,36 mm., 0,34 mm. and 0,62 mm. long, the chela 1 mm. long (palm 

 0,42 mm., fingers 0,58 mm.); of the left leg the segments are 1 mm., 0,6 mm., 0.4 mm., 

 0,36 mm. and 0,6 mm. long, the chela 0,97 mm. (palm 0,44 mm., fingers 0,53 mm.). These 

 numbers show that, like in the variety laetabilis, the fourth segment is distinctly shorter 

 than the 2 ml . 



The relative measurements of the 3 vd pair are: merus 1,4, carpus 1, propodus 1,3, so 

 that both the merus and the propodus are a little shorter in proportion to the carpus than in 

 the other female from this Station, referred to the variety lactabilis. The merus is 7,2-times 

 as long as broad, the carpus 7-times as long as thick, the propodus 1 i-times as long as broad 

 and provided with 8 pairs of spinules. The dactylus measures one-third of the propodus and 

 is 6,2-times as long as broad at base. 



This specimen is probably an individual variety of the laetabilis-ioxva. ; when, however, 

 it should prove to be constant, a proper name must be created.

Stat. 220. November 1/3. Anchorage- off Pasir Pandjang, west coast of Binongka. 54 m. 

 Bottom coral sand. 1 male. 



This specimen is 7,85 mm. long from tip of rostrum to tip of telson (carapace 2,65 mm., 

 abdomen 5,2 mm.), the abdomen being only about twice as long as the carapace. Rostrum 

 and orbital spines like in the specimen from Stat. 279, described in 191 1. Second antennular 

 article twice as long as thick, just as long as the visible part of the i st ; 3 rd article a little 

 more than two-thirds of 2 nd . Antennal peduncle and terminal spine of scaphocerite almost 

 reaching to the tip of the antennular peduncle. 



Large cheliped lost. Merus of the small (left) cheliped 3,5-times as long as broad in 

 the middle, when measured along the upper border of the outer surface, that ends in an acute 

 tooth ; infero-internal margin with 6 or 7 small spinules along its whole length. Chela 1,9 mm. 

 long, one-fourth the length of the body, fingers as long as the palm. 



Carpal segments of the right leg of the 2 nd pair 0,5 mm., 0,36 mm., 0,18 mm., 0,2 mm. 

 and 0,28 mm.; chela 0,66 mm. (palm 0,28 mm., fingers 0,38 mm.). Merus of this leg 1,15 mm. 

 long, broad in the middle 0,14 mm., 8-times as long as broad. 



Relative measurements of the 3 rd leg: merus 1.85, carpus 1, propodus 1,4. Merus
