equal; the claw is long and strong. Pereopods III are more than 1.5 times 

 longer than pereopods II, their 2nd segment is almost equal to the 4th and 

 5th segments together; the narrower 6th segment is almost twice longer 

 than the 4th; the claw is long, strong, and slightly curved. Pereopods IV 

 are longer than pereopods III because of the greater length of the distal 

 segments. Pereopods V are shorter than IV but the distal segments (partic- 

 ularly the 6th) are markedly massive; the 2nd segment is equal to the 4th 

 and 5 th together and slightly longer than the 6th; the 6th segment is very 

 broad, almost linear and forms with the claw a well-developed subchela; 

 its palmate margin is shorter and steeper than in the Microphasma and 

 armed with a row of strong, short setae, increasing in size in the distal part 

 of the row; the length of the strong curved claw is less than the width of 

 the 6th segment. Pereopods VI are slightly shorter than pereopods V and 

 much weaker; their 2nd segment is equal to the 4th and 5th together and 

 slightly longer than the markedly distally narrowing 6th segment; the claw 

 is long, strong, and curved. Pereopods VII are the same in structure and 

 length ratios of segments as pereopods VI but only 2/3 their length.
