EUROPEAN" FORMS OF THE CIROLiXIN^. 353 



Grampus griseus. I applied to the zoological authorities ia 

 Marseilles in order to obtain Grourret's types for study, but in 

 spite o£ careful searching they could not be found and are 

 probably lost. His description and most of his figures are not 

 sufficient for recognition of the species ; but according to his 

 fig. 9, which represents the abdomen and one of the uropoda, 

 the animals do not belong to ConiJera, but are young stretched 

 specimens of Cirolana Cranchii.

Head more or less angular in front of the small black eyes. 



Erontal plate very large, slightly longer than broad, increasing 

 much in breadth from the middle to the anterior end, which is 

 cut off with the front margin slightly concave. Between this 

 lower front margin and the anterior end of the process (between 

 the antennulse) from the upper surface of the head the frontal 

 plate shows a triangular surface looking forwards, and this sur- 

 face is partly visible when the head is seen from above. . On the 

 lower side of the plate the lateral margins and the front margin 

 are thickened, forming elevated ridges between which an 

 impressed area is seen. 



Clypeus anteriorly produced into a triangular, basally very 

 broad and distally rounded, nearly lamellar process, which pro- 

 ceeds downwards and forwards below the basal part of the frontal 

 plate. 



Antennulae slender, somewhat longer than the peduncle of the 

 antennge ; peduncle three-jointed ; the flagellum consists of four 

 proportionately long and some minute joints. 



Antennae do not reach to the middle of thorax ; flagellum 

 about as long as the peduncle, with eleven joints. 



Epimera of the thoracic segments increase in size and in the 

 degree of being produced backwards from the second to the 

 sixth, while the seventh is considerably smaller than the sixth. 

 All epimera are strongly carinated, and the posterior pairs rather 

 excavated behind their oblique carina.
