De Man, who perfectly recognized that his specimens were identical 
with Ses. ricordi, with the type-specimen of which he could compare 
them, nevertheless described them under the name Ses. angustipes, con- 
vinced that the species of Dana was identical with that of Milne-Edwards. 
Miss Rathbun, who had oceasion to examine a large number of American 
specimens of Sesarma, and among these the type specimen of Ses. ricordi, 
declared this and Dana’s species to be distinct (see Proe. Biol. Soc., v. 
11, 1897, p. 90—91). Under the head of Ses. cinerea (Bosc) I have al- 
ready referred to the great confusion existing between the three species 
here named, and continued until Miss Rathbun cleared the matter. All 
three species, together with the closely related Ses. roberti H. Milne- 
Edwards and Ses. reticulata Say seem to be common along the east coast 
of the United States and on the numerous West-Indian islands, but only 
Ses. reticulata extends as far north as New Jersey and New Haven.
