besetzt, die an der Basis viel kleiner sind und dichter stehen als am Ende. Die

 Pigmentflecken auf dem letzten Abdominalsegmente vorhanden, 



Verbreitung: Die Art ist von der norwegischen, britischen und fran- 

 zösischen Küste, aus dem Mittelmeere und dem schwarzen Meere bekannt. 



Gattung Bathymysis Tattersall. 

 1907, Bathymysis W. M. Tattersall, Ann. nat. bist. ser. 7, v. 19, p. 116. 



„Carapace evenly rounded in front, without any trace of rostral projection. 



Eyes set close together, apparently without definite eyestalks, somewhat 

 flattened and subquadrangular in shape; visual Clements imperfectly developed and 

 unpigmented in preserved spccimens. 



Antennal scale shortly lanceolate in shape, setose all round. 



Mouth-organs and first and second thoracic limbs as described by Sars for 

 the genus Leptomysis, except that the terminal Joint of the palp of the second 

 maxilla is expanded at its apex and armed with numerous short stout spines, the 

 whole appendage being generally as figured by Sars for Schistomysis spiritus. 



Tarsus of the remaining thoracic limbs four-jointed; nail long and slender. 



Telson fairly long; very deeply cleft, the cleft serrated; lateral margins armed 

 throughout their length with spines. 



Inner uropod with a row of spines all along its inner margin. 



Pleopods in the male exactly as for the genus Leptomysis." (1. c.) 



83. Bathymysis helgae Tattersall. 

 1902. Bathymysis helgae W.M. Tattersall, Ann. nat. bist. ser. 7, V. 19, p. 116— 118. 



„Carapace covering all the thoracic segments; evenly rounded in front and 

 at the antero-lateral corners; without trace of rostral projection. 



Pleon longer than the carapace; the first segment equal in length to the 

 fifth and slightly longer than the subequal second, third, and fourth segments; 

 sixth one and a half times as long as the fifth. 



Eyes strongly recalling those of Amblyops, rather small, somewhat flattened 

 and subquadrangular in shape, not reaching to the distal end of the first Joint of 

 the antennular pcduncle; apparently without definite peduncles; set very close 

 together; visual Clements imperfectly developed and without pigment in preser- 

 ved specimens. 



Antennular peduncle a little shorter than the telson, moderately stout, third 

 Joint equal in length to the basal two combined; male appendage well developed 

 and densely hirsute. 



Antennual peduncle a little shorter than the antennular, slender, the second 

 Joint one and ä half times as long as the third.
