Indeed I have seen in museums specimens alleged to be L. galei , far exceeding 
these in size. 
Again in the ovisacs there are more eggs in a row than in L. scyllicola , 
viz. 29 or 30, as compared with 22 to 23 in the latter species. The individual 
ova are smaller than in L. scyllicola. 
The only appendages of specific value are the mandibles and the maxilli- 
pedes: 
The mandibles (Fig. 3 b) were very accurately described by Kurz, who 
distinguished three kinds of teeth: (1) principal teeth (Hauptzahne), much 
the largest, hatchet-like, usually curving backwards and alternating with 
(2) intermediate teeth (Zwischenzahne), which are very minute, serrate, 
triangular in shape, and occupy the base of the angles between the principal

teeth; (3) secondary teeth (Nebenzahne), which follow in a continuous 
sequence behind the principal teeth diminishing regularly in size towards 
the proximal end of the mandible. In L. galei there are: one principal tooth 
(terminal), an intermediate tooth; three principal teeth with two intermediate 
teeth respectively between them, one between each; three secondary teeth. 
The maxillipedes (Fig. 4 b) in my estimation, do not agree with the 
figures of Scott and Scott very closely. They consist of a basal joint which 
I should not describe as stout but only moderately so, and a terminal joint, 
not very powerful, terminating in a curved claw smaller than in other species, 
having at its base an accessory claw which is not ventral as in other species, 
but is situated on a lateral projection, as figured by Scott and Scott, who 
have (possibly intentionally) exaggerated it, and two smaller spines at the 
base on the side of the concavity. The terminal joint has the usual cushion
