302 GEORGE HODGE ON NEW MARINE ACARI, 
short stout hairs. Legs and rostrum irregularly dotted 
with minute granules; other markings varied in char- 
acter. The posterior portion of body minutely corrugated, 
and delicately sulcated witha broad curved band, approach- 
ing the origin of second legs; above the sulcus are 
irregular cell-like markings, by degrees becoming less 
visible as they approach the rostrum. 
Hye, a single dark speck behind the rostrum. 
This curious species occurred on some stems of Coryne eximia 
from between tide marks; and from the specimen obtained 
possessing only three pairs of legs, it would appear to be a young 
individual. 
Genus. LEPTOGNATHUS. 
4, Li. Fatcatus. Pl. XVI. fig, 6, 7. 
Length of animal to tip of rostrum, 3), of an inch; colour, 
orange brown. Shield truncate above insertion of first 
legs. Rostrum, a stout bulb tapering to a narrow rounded 
tip, which under pressure is seen to be bifid; external to 
this are two palpi-like organs, consisting of a joimted 
process closely attached to the rostrum, terminal joint 
slightly curved, divergent from rostrum, and furnished 
with three stout hairs. From the narrow part of the 
rostrum proceed two hairs, which stand out at right angles. 
Legs rather short for size of the animal, the several joints 
scarcely differing in length, with the exception of the 
sixth, which is long, thin, and terminated by two ungues 
of simple character; at the tip of last joint, near the 
origin of the ungues are four stout bristles. 
Hyes three, compound,* one being immediately behind the 
base of the rostrum, the other two behind the second pair 
of legs; the anterior eye composed of four minute granules, 
the largest about 7,455 of an inch in diameter; the lateral, 
* Mr. Gosse, in his Marine Zoology, in defining the characters of the Marine Acari, says 
they have not “‘ compound eyes; ” this would however need some modification, or that the word 
compound should be used in a more restricted sense than is generally done—possibly he 
means that the eyes of these animals are not compound after the manner of the compound eye 
of a crab or shrimp, still it is an undoubted fact that some of the Marine Mites have visual 
organs composed of a number of lenses irregularly grouped, so as to form a composite eye.
