The 2nd Antenna (Fig. 6) consists of a basal joint bearing a large unjointed 
endopodite with a round or blunted end, and a small exopodite whose 
diameter is half that of the endopodite, and which is distinctly two jointed, 
the terminal joint being a claw which forms a true chela in conjunction with 
a spine projecting from the penultimate joint. 
The Mandibles (Fig. G) precisely re¬ 
semble those of the female. The teeth 
appear to be vestigial. 
The 1st Maxilla (Fig. 6) consists of an 
unsegmented endopodite, and an exopo¬ 
dite or palp which is two-join ted and 
tipped with a large mammillated claw 
and two small subsidiary claws. The en¬ 
dopodite is tripartite at the distal end, 
the outer ramus being terminal, and the 
other two on the inner margin. Each 
ramus ends in a long mammillated claw. 
The 2nd Maxilla (Fig. 7) is stout, two- 
jointed, with a large spinous process on 
the basal joint for the apposition of the 
terminal claw. 
The Maxillipedes (Fig. 7) closely re¬ 
semble the 2nd maxillae. They are two- 
jointed, and again the terminal claw is 
curved and fits against a process on the 
basal joint which is not spiniferous. They 
are not appreciably larger than the 2nd 
maxillae, as in most species. They arise 
close to the bases of these maxillae and 
are swollen and fleshy, terminating in an 
auricular disc. The two discs approxi¬ 
mate at the inner edge, and thence con¬ 
jointly give rise to a saucer-like tenaculum. 
The musculature of the appendages is seen from Fig. 8, and calls for no 
comment. It is much more powerfully developed than in the female. 
The unpaired median nauplius eye is retained in these males. Kane also 
found it in L. bidiscalis\ but none of the male Lernaeopods described by 
Wilson (1915) are figured as possessing such an organ. A very noticeable optic 
nerve connects it with the supra-oesophageal ganglion. The eye appears pink. 
The Mouth parts. The mouth forms a suctorial proboscis situated at 
the summit of a cone which is bent at right angles to the cephalothorax, so 
as to be directed downwards. There is an upper and a lower lip each of which 
is bordered by setae of characteristic shape. In appearance it exactly resembles 
that of the female q.v.
