500 DR. R. O. CUNNINGHAM ON THE REPTILES, 
as in C. linearis. Three preceding segments shorter, and rather wider than in C. 
linearis. 
Taken in the mouth of a Flyingfish to the south of the Cape-Verdes. The specimen is 
an ovigerous female. 
19. PTERELAS MAGNIFICUS, Dana. 
I obtained specimens of this handsome species on fish of various species at Fortune 
Bay (west coast of Patagonia), and at Dungeness (eastern entrance of Strait of Magellan). 
80. CrROLANA HIRTIPES (?), Edw. 
An imperfect specimen of a Cirolana which, I think, is referable to the above species 
was taken on a fish at the Tyssen Islands, Falkland Sound. 
81: NEROCILA FALKLANDICA, n. sp.’ (Pl. LIX. fig. 2.) 
Last two segments of pereion CRAT with acute points. "Three last epimerals acute. 
Pleon longer than broad. The first two segments laterally produced, and armed 
with acute points. The last segment somewhat triangular, emarginate at the tip. 
Caudal appendages aculeate; the outer are considerably the larger. 
Taken on a fish in Falkland Sound, by one of the officers of H.M.S. * Narcissus.’ 
ENTOMOSTRACA. 
82. CYPRIDINA GIBBOSA, Dana. 
Taken in the towing-net between Monte Video and the Strait of Magellan, December 
1866. 
SIPHONOSTOMA. 
83. CALIGUS CHJENICHTHYIS, n. sp. (Pl. LIX. fig. 15.) 
The general form of this species, apparently undescribed, will be better understood by 
the figures than by any description. The cephalic buckler is deeply horseshoe- 
shaped posteriorly. 
The two specimens figured are, 1 baliate, male (5) and female (a), and were taken on 
Chenichthys esox, in Port Grappler, west coast of Patagonia. 
84. LERNÆA, sp. (Pl. LIX. fig. 11 a, b.) 
The two Lerneans figured were taken on the gills of fish in the Strait of Magellan ; 
but as the species of this genus vary very much in form, I have thought it more prudent 
not to name the species. 
85. LERNJEOCERA, sp. (Pl. LIX. fig. 10.) 
The specimen figured was found attached to the eye of a fish Dia at the Otter Islands, 
west coast of Patagonia. 
86. CHONDRACANTHUS, sp. (Pl. LIX. fig. 13. Two views of an individual, and a pot 
of one of the ovaries.)
