248 Transactions. — Zoology. 



The mandibles are indistinctly 3-jointed ; the first two joints project 

 horizontally forward in front of the proboscis ; the 3rd is placed at right 

 angles to the 2nd, and the nipping claws are at right angles to it and work 

 horizontally in front of the month. The palpi are represented by a small 

 tubercle at the base of the mandibles on each side. 



The ovigerous legs are about 10 mm. long, and are present in both 

 sexes. They are 8- (? 9-) jointed, the four terminal joints being furnished 

 with simple short spines. 



The legs of the 3rd pair are 31 mm. long, the relative lengths of their 

 joints being as follows : — 



1, 2, 3, 4, 5, 6, 7, 8, 



2. 6. 3. 16. 17. 18. 1. 5. 



The upper margin of the 2nd tarsal joint protrudes somewhat beyond the 

 articulation of the claws. 



The integument of the body and appendages is everywhere more or less 

 furnished with spines of varying size and strength ; these are most nume- 

 rously developed on the mandibles. 



Hob. Lyttelton Harbour, taken by the dredge. I am indebted to 

 Dr. E. von Lendenfeld and Mr. C. Chilton for several specimens of this 

 species.
