Fig. 116. Vibilia bovallii Bonnier, male (after Bonnier, 1896). 



The species was described from two specimens about 10 mm in 

 length. 



The body is bulged and tapers backward. The head lacks a rostrum 

 and has highly developed pyriform eyes. Antennae I have a short base 

 with a shortened 2nd segment; the 1st segment of the flagellum is ovally 

 broadened and the rudimentary 2nd segment barely perceptible apically. 

 antennae II are somewhat longer than antennae I, their flagellum three- 

 segmented. 



The 2nd segment of pereopods I is strong and not broadened; the 

 4th-5th segments are without a process; the 6th segment has a dentic- 

 ulate posterior margin; the claw is strong and curved. Pereopods 11 are 

 similar to pereopods I but the 4th segment has a spatulate lobe extend- 

 ing almost to the distal margin of the 5th segment; the 5th segment is 

 without a process — which is the most typical character of this species. 

 Pereopods III-IV are identical, somewhat shorter than the subsequent 

 pairs. Pereopods V-VII differ little in length, pereopods VII being just 

 slightly shorter than the preceding ones; the 2nd segment is broadened, 

 very much so in pereopods VII, with minute spinules distally on the 

 anterior margin; the anterior margin of the 6th segment in V-VI pairs is 

 finely denticulate; the 7th segment in VII pair is covered with minute 

 squamose formations with incised margins.
