The specimens dredged near New Zealand, in deep-water (Station 167), are generally 
of larger size, and in most, but not all of them, the tubercles of the gastric and branchial 
regions are less prominent and the chelipedes are more developed than in the specimens 
from Australian localities. 
In small females the two rounded protuberances of the posterior margin are not 
developed, and the margin is straight. 
There are in the collection three small females from the Agulhas Bank, 150 fathoms, 
lat. 35° A 0" S., long. 18° 37' 0" E. (Station 142), which cannot, I think, be distinguished 
specifically from Ebalia tuberculosa . 1 
Ebalia ( Phlyxia ) crassipes (Bell). 
Plilyxia crassipes, Bel], Trans. Linn. Soc. Lond., vol. xxi. p. 304, pi. xxxiv. fig. 2, 1855 ;

„ ,, Miers, Crust, in Rep. Zool. Coll. H.M.S. “Alert,” p. 252, 1884. 
Specimens of this, which is perhaps the commonest species of the subgenus (or genus) 
Plilyxia were obtained at the following localities : — 
Port Jackson (Sow and Pig’s Bank), 6 fathoms, a good series of specimens; also 
at Port Jackson, 8 to 15 fathoms (an adult male), and 30 to 35 fathoms (two adult 
males) ; also several males and females dredged off the South Australian coast in 2 to 10 
fathoms, in April 1874 ; and several specimens from East Moncoeur Island, Bass Strait, 
38 fathoms (Station 162). 
In the adult males the chelipedes are often very considerably elongated ; one in 
the Challenger series from Port Jackson (30 to 35 fathoms) presents the following 
dimensions : —

The carapace is always more or less distinctly tuberculated on the dorsal surface, with 
greyish or fuscous markings, which exist also on the chelipedes. 
1 j Ebalia tuberculosa is connected through Ebalia fragifera, Miers (Ann. and Mag. Nat. Hist., vol. viii. p. 268, 1881), 
with Ebalia tuberculata, and certain other Atlantic and European forms. Ebalia fragifera is, however, distinguished 
from Ebalia tuberculosa by the deeply concave hepatic regions of the carapace, the less prominent front, and the fewer 
granules of the palms of the chelipedes. The Mascarene (Providence Island) specimen referred by me to Ebalia 
granulata, Riippell, differs somewhat in the broader carapace, less prominent front, &c.
