"At the Bermudas the Ligia occurs in great abundance on the 

 ledges and cliffs along all the shores. It runs with surprising activity 

 and quickly seeks refuge in the cracks and crevices of the ledges, so 

 that it is not easy to capture without injury. 



Its dark, bluish -gray color is not particularly protective here, 

 unless in the night, owing to the light color of most of the rocks, 

 but on darker rocks it would he decidedly protective." A. E. V. 



It is doubtful if the specimens found at Cayenne by Miers* and 

 identified by him as Ligia baudiniana really were that species. 

 I am inclined to think they should be referred to Ligia exotica. In 

 his description of them, Miers states that the antennae are very long, 

 reaching in one specimen to the extremity of the bod}?", and in the 

 other specimen not quite, hut almost to the extremity. The first 

 was probably the male and the other the female of L,. exotica. 

 There has been much difference of opinion in regard to these two 

 species, Ligia baudiniana and Ligia exotica, the former being con- 

 sidered by Budde-Lundf and DollfusJ as a synonym of the latter, 

 although Dollfus states of the specimens found at the Bermudas, and
