LEPTOMITHRAX WAITEI (Whitelegge). 



Chlorinoides waitei, Whitelegge, Mem. Austral. Mus., iv., 

 1000, p. 143, pi. xxxiii. 



Between Port Stephens and Newcastle, New South Wales, 

 22-60 fathoms ; one female. 



Off Babel Islands, eastern slopes, 70 fathoms ; one female. 

 Total length of carapace 130, total width 109.2 mm. ; length 

 of first ambulatory leg 162, of last leg 126 mm. 



The carapace of these large females is longer in proportion 

 to its width than in the large male measured by Whitelegge. 

 The .submedian series of spines includes two pairs on the 

 protogastric regions, those of the hinder pair being the 

 smaller and further apart. 



LEPTOMITHRAX GLOBIFER, sp. nov. 



(Plates x. and xi.) 

 Type-locality. Southern Australia 23 ; one male, ho lo type. 



Measurements. Male holotype, length of carapace, includ- 

 ing spines, 86.6, lengthen the median line 71, width without 

 spines 56 mm. 



Diagnosis. A round excrescence on merus of outer maxilli- 

 ped. Four marginal spines on branchial region. 



Description. Carapace ovate-oblong ; covered, but not 

 crowded, with acute tubercles and a few spines ; four large 

 spines forming a semicircle on the margin of the branchial 

 region, the posterior of these spines being subdorsal ; hepatic 

 region outwardly produced, margin armed with two spines, of 

 which the anterior is the larger ; four small median spines, two 

 mesogastrie, one urogastric and one intestinal ; ten pairs of 

 submedian spines and tubercles (three frontal, or between the 

 orbits, two protogastric, two mesogastrie, one cardiac and two 

 intestinal), the last pair being stout spines which project 

 horizontally backward. 



Rostral spines gradually tapering, slightly divergent and 

 one-fifth as long as the remainder of the carapace. Surface of 

 preorbital lobe covered with sharp granules, spine long and 

 projecting transversely, separated by a narrow gap from the 

 middle supraorbital spine. This last is narrow-triangular, 

 bears one or two erect spines or spinules at its base, and is in 

 contact at its middle with the postorbital cup ; between the 



22. In allusion to the rounded excrescence on the mouth. 



23. The details of the locality and, date associated with this specimen are 

 incongruous. It was almost certainly secured in southern Australian waters.
