New England &c., in the sixth part of the Eeport of the U.S. Fish 

 Commission (1880). 



The ^ga Sarfordi of Lockington (Pr. Cal. Acad. Sci. p. 46, 

 1877) is designated Idotcea Sarfordi in a MS. note of the author, 

 and the short description woukl apply in most particulars to a 

 species of Ghjptonotus . Specimens, however, are in the British 

 Museum from Sta. Eosa Island, received from Mr. Lockington, 

 which certainly do not belong to any genus of Idoteidce, but to 

 Cirolana or a closely allied type. Can it be that two distinct 

 species were confounded under one name ? 



Subfamily II. IDOTEINJE. 

 Sides of the liead in a dorsal view entire and not laterally pro- 



duced. Eyes lateral. Leys all ambiolatory ; the three anterior 



pairs with the penultimate joint not dilated.

 certain of the species of Glyptonotus.
