Lernaeopoda globosa n. sp. 
being long and slender, they are short and thick, only as long as the trunk, and 
end bluntly in a cigar-shaped manner. They contain 6-8 rows of but 12 eggs 
each. The eggs are comparatively large, spherical, and slightly flattened at 
the poles. Each of the specimens taken from the nasal grooves (but not the 
one near the spiracle) bore but one ovisac. This is probably not normal, 
since both ovaries were fully developed, but due to the confined space in which 
they were located. 
The male dogfish in whose nasal grooves the representatives of this new 
species were discovered, possesses three specimens of L. scyllicola, two of them 
with attached males, in its extra-cloacal aperture. 
Generic characters of female. See Parasitology , vm. 272. 
Specific characters of female. Size small (5-6 mm.). Cephalothorax at 
right angles to the trunk axis. Second maxillae nearly as long as the body, 
much curved, and expanded at the tips into large cupuliform discs which 
unite with a minute vestigial bulla. Abdominal appendages almost filiform 
and minute (0-5 mm.), less than a quarter as long as the ovisacs. Ovisacs 
short and broad, of the same length as the trunk (a little over 2 mm.). Trunk 
globose or pear-shaped. Second maxillae much bent in a characteristic 
attitude instead of being raised straight above the head. Mandibles with a 
few curved teeth. Maxillipedes with a specific spine on the outer edge of the 
terminal joint, and a small spine on the basal joint, which is stout, where 
L. scyllicola has a large curved hook.
