ISOPOD8 OF NORTH AMERICA. 657 



very large, triangular in shape, the basal joint of either uropod meeting 

 in the median line at the upper inner angle. From this angle the inner 

 branches of the uropoda extend in the form of narrow elongate 

 processes, broader at the apex than at the base and not quite reaching 

 the posterior extremity of the terminal abdomi- 

 nal segment. 



A single specimen, a female, was collected by 

 Messrs. Palmer and Riley in Nueva Geroua. Isla 

 de Pinos, Cuba, July 10, 1900.

This species differs from the type species of VIEW OF ABDOMEN x 5 . 

 the genus, Pxeudarmadillo carinulatus Saussure," 



in the presence of two longitudinal rows of long stout spines on the 

 thorax, a row on either side of the median line halfway between 

 that and the lateral margin, while in the description of P. carinulatus 



only two tubercles (not spines) are mentioned 

 as being present on the thorax, the last thoracic 

 segment alone being armed with two large tri- 

 angularly shaped (triquetres) tubercles; in the 

 absence of the longitudinal carina?, mentioned

ments and the third abdominal segment; in the 



presence of a large spine on the fifth abdominal segment in the median 

 line, which is represented in P. carinulatus by a strong tubercle, and 

 in the presence of eyes, which are wholly wanting in P. ca f nnulatus. b 

 Named for Dr. Theodore Gill, the eminent naturalist. 



PSEUDARMADILLO DOLLFUSI, new species. 



Body ovate, about twice as long as wide, 5 mm. : 10 mm. 



Head two and a half times wider than long, 1 mm. : 2 mm., with the 

 anterior margin produced into three lobes, one median lobe, which is 

 truncate and broad, and two smaller lateral lobes, which are rounded. 

 The eyes are small, round, composite, and distinct, and situated close 

 to the lateral margins. The head is covered with tubercles, of which 

 there is a prominent line on the posterior margin. The first pair of 

 antennae are inconspicuous; the second pair have the first article short, 

 the second twice as long as the first; the third and fourth are subequal 

 and each is a little shorter than the second; the fifth is nearly twice as 

 long as the fourth. The flagellum is composed of two articles, the first 

 of which is one-third as long as the second.

 in error when he described the species as being without eyes.
