amalgamated a little longer than the preceding one, narrowing 

 somewhat distally and constricted above into a small truncated 

 telson, which, however, does not project beyond tlie extremity, 

 and is almost hidden in lateral view ; this bears on its upper 

 surface two transversely placed stout spines and many long 

 setae ; below this piece on each side is a stout marginal spine, 

 and the margins thence curve downwards and forwards to the 

 base of the uropoda, and are fringed by a single rather stout 

 spine, and several spinules and setae. 



The inferior margin in front of the uropoda, curves evenly 

 upwards and bears a series of two stout and about four liner 

 simple spines. Uropoda with rami shorter than the basal joint, 

 inner one slightly the longer, its upper surface swollen at the 

 middle area and bearing two stout spines, outer ramus with one 

 spine on the upper surface. 



Upper antennae not reaching to the extremity of the fourth 

 joint of the lower antennae, peduncle short, flagellum of about 

 seven joints. Peduncle of lower antennae long, possessing few 

 setae, the fifth joint longer than the fourth ; flagellum multi- 

 articulate (length unknown). 



Gnathopoda of male with hand very large and ))0werfu], sub- 

 triangular, narrow at the insertion of the finger, palm oblique, 

 concave, margin entire, and fringed with long spineform setae, 

 meeting the posterior border in a clearly defined obtuse angle ; 

 anterior and posterior margins evenly convex. Finger a little 

 shorter than the palm, impinging against the inner side of the 

 hand beyond the palmar edge, its inner surface near the middle 

 tumified. 



Colour. — Spirit specimens, creamy white. 



Length. — Male, 15-5 mm. 



Habitat. — Near Zeehan, Tasmania, in burrows of Engaeus aini- 

 cularius. (Received fron Professor W. A. Haswell.) 



Supplementary Description. 



I received three specimens, and each appears to be a male, in 

 consequence of having a large hand agreeing precisely with each 

 other. The largest one measured 15-5 mm. in length, and the 

 other two about 12 mm. ; one of these latter I dissected ; it was 

 a male, and the following description is taken from it.
