inoutli closely agree with those of yE(fa psora, as figured Ijy Hars 

 on pi. 24. The maxillipedes have six well defined joints ; the 

 .seventh if present is very small. 



First pair of legs the shortest, and 

 somewhat less robust than the two 

 following pairs ; basos joint of the 

 first a little more than twice as long 

 as broad, with a sharpl}' defined ridge 

 on the e.xternal surface, terminating 

 distally in a prominent rounded lobe. 

 Ischium joint with a small superior 

 distal lobe tipped 

 by a spine ; both 

 the lobe and the 

 spine are greatly 

 developed on the 

 same joint of the 

 second and third 

 legs. Merus of 

 the first leg un- 

 armed, the second 

 and third with 

 two or more 

 spines on both 

 upper and lower 



distal extremities, and three or four 

 on the middle portion of the lower 

 border. Carpus armed with one spine 

 inferiorly and the propodus with two. 



Fourth to seventh pairs of legs very 

 similar. The superior and inferior 

 distal extremities of the ischium, 

 merus and carpus of the sixth are 

 armed with a fringe of from six to 

 twelve spines ; the lower borders also 

 carry two or more moderate spines, 

 with one or two small accessory 

 spinules on either side in the same 

 transverse line. A row of similar 

 spines and spinules occurs on the 

 lower border of the propodus. Pleo- 

 pods densely fringed with longish 

 hairs. Outer ramus of the first pair 

 longer and broader than the inner. 

 Uropods projecting slightly beyond 

 the telson. Outer ramus shorter o..,.,. t.„ 



and much narrower than the inner ; Fig. 20/.
