200 THE SCHIZOPODA. 
number of features from the description and figures published by Sars, I asked 
my friend the excellent carcinologist Dr. W. T. Calman to examine the type 
preserved in the British Museum. I sent him tracings of my figures published 
in this paper of my specimen, together with a number of questions on particular 
features. Dr. Calman answered that the type ‘‘agrees better with your deserip- 
tion and figures than with those of Sars in all the points you mention,” and he 
added some notes and sketches which agree well with the features observed in 
my specimens. Therefore I will now give the following additions to the deserip- 
tion of Sars. 
The front margin of the carapace (fig. 5a) is furnished with spiniform 
processes or denticles, those on the most lateral fourth of each half of the margin 
are long and slender, and from here they decrease very much in size, being 
quite minute along a part of the margin towards the proportionately narrow 
and very short frontal plate which is produced into a rather slender and some- 
what long, acute rostrum. The posterior margin of the carapace has a number 
of small or very small denticles, while the posterior margin of its lateral wings 
and the lateral margins are unarmed. 
The eyes (fig. 5b) show peculiar features. The postero-lateral area of 
ocelli is, seen from above, a little more than half as long again as broad; there 
is no interval between the anterior and the postero-lateral area; the most pos- 
terior row of facets of the anterior area is of normal aspect, while each facet 
in the four following transverse rows of the anterior area is produced into a 
somewhat small, acute denticle; all other facets on the upper surface of the 
eye are simple, rounded. From the inner margin of the eye-stalks a little before 
the ocelli a very oblong, weak process or appendix projects forwards; in the 
adult female it is about as long as the part with spine-bearing ocelli on the 
opposite lateral margin.— The antennal squama (fig. 5c) is three times or a 
little more as long as broad, with the outer margin scarcely concave, the terminal 
lobe slightly broader than long and the outer distal process as long as, or a little 
shorter than, the terminal lobe and bent slightly outwards.— The thoracie 
legs (fig. 5d) on the outer side with a good number of moderately long setae; 
the distal half or one third of each of these setae is quite naked, while the re- 
mainder is very closely plumose; along the inner side of the legs the setae are 
less numerous, but several among them are very long, and all are naked or with 
extremely short hairs along the distal side.
