16 Mr. H. W. Bates on the Longicorn 



antennae about half the length of the animal in the female and 

 more than three fourths in the male. Mandibular with a molar 

 tubercle. The lirst and second gnathopoda resembling those 

 of Callisoma liopd and G. crenata. The coxje of the five 

 anterior pairs of appendages the same as in the above-named 

 species ; but those of the fourth pair of pereiopoda considerably 

 deeper than the ones appertaining to the fifth pair. The 

 meros in the first two pairs of pereiopoda is ])roduced an- 

 teriorly, and those of the three succeeding appendages, as well 

 as the carpus of the third pereiopos, are produced posteriorly 

 into a squamose plate. The basis in the last three pairs of 

 pereiopoda nearly the same as in Callisoma crenata., but the 

 basis in the fourth pair considerably broader and higher than 

 in the fifth pair. The fourth segment of the pleon, very 

 much smaller than the preceding, has a notch on its dorsal 

 surface and close to its junction with this segment ; the fifth 

 segment, still smaller, is also remarkable by a like but much 

 less deep notch. The pleopoda of the sixth pair biramous, 

 the rami being subequal, subfoliaceous ; the inner one shorter 

 and fringed on its inner margin with plumous hairs ; the 

 outer margins of both branches bear three to four spinules. 

 Telson deeply cut, but single. 



The wiiole animal is covered with brownish-yellow, minute, 

 subovate spots, very regularly disposed, particularly on the 

 segments of the pleon. The dead specimens preserved in 

 spirit are yellowish grey, the others preserved in glycerine 

 tending to a lemon-colour. 



Length of the male 7*54 millims., of the female 8*22 

 millims. 



The specimens were taken by Count Constantine Branicki 

 at Nice in a dead Clypeastevj and presented to the Zoological 

 Museum at Warsaw. 



Being desirous of associating with the discoveiy one who 

 has done so much for the advancement of natural history in 

 his own country, and contributes so profusely to the enriching 

 of our country museum, I have attached to the species the 

 name of Count Constantine Branicki.
