gin of the anal valves to the apex of the telson. The distance from 

 the same point to the base of the telson may be conveniently, if not 

 quite accm'ately, called ''pre-anal." 



The bibliographical data under each species include, as a rule, 

 references to (1) the first description of the species, (2) the fullest de- 

 scription hitherto published, and (3) the chief records of its occurrence 

 in American waters. No attempt is made to give the full synonymy 

 for each species. 



Following the practice of the United States National Museum, a 

 single individual has been selected and labeled as the "holotype" of 

 each of the new species here described. It will be readily under- 

 stood, however, that this specimen is not in all cases that from which 

 the drawings have been prepared or that to which the dimensions re- 

 corded in the description apply. The drawings often combine feat- 

 ures taken from several more or less imperfect specimens, while the 

 descriptions are based chiefly on specimens selected for dissection 

 and partly or completely destroyed in the process. 



BODOTRIA, ? species. 



A single female specimen of an undescribed species of this genus is 

 in the collection from Japan, but, as it lacks the uropods and is other- 

 wise imperfect, it can not be fully described. It has a strongly marked 

 lateral ridge on the carapace as well as on the thoracic somites, differ- 

 ing m this from B. pulex Zimmer, the only species hitherto recorded 

 from Japan. It is also distinguished from all the knoA\Ti species of 

 the genus by having the carpus of the first legs expanded and about 

 one and one-half times as broad as the merus.

CYCLASPIS LONGICAUDATA G. O. Sars. 



Cyclaspis longicaudata G. 0. Sars, Forh. Vidensk. Selsk. Christiania, 1864 (1865),

This species has not hitherto been recorded from the western side 

 of the North Atlantic, although, as an inhabitant of the deeper 

 waters, its occurrence there is not surprising. It may not be without 

 significance that at all the stations off the American coast the depth 

 exceeds the maximum (1,450 fathoms) hitherto recorded for the 

 species off the European coasts.
