FIGURE 4. Eumttra chamberlaini A. H. Clark, U.S.N.M., 35927: a, Laterodorsal view of centrodorsal; b, proximal 

 part of postradial series; c, peripheral cirrus; d, Pj; t, PI; f, PI; g, PI. 



twice as broad as long, the second is about as long as broad, the third is ratlior longer 

 than broad, and the remainder are about twice as long as broad. 



P 3 is the longest and stiff est pinnule, 13 mm. long with 20 to 22 segments, of which 

 the first is short, the second about as long as broad, and the following increase in length, 

 so that the fifth and those succeeding are about twice as long as broad, becoming slightly 

 longer distally. P< and P 6 resemble P 2 . The distal pinnules are 9 mm. long with 18 or 

 19 segments, of which the first is very short, the second is about as long as its proximal 

 breadth, slightly trapezoidal, and the third and following are greatly elongated and very 

 slender with slightly expanded articulations. 



The color in alcohol is (a) yellow, the cirri white, and the perisome brown, or (6) 

 brownish yellow, the cirri and pinnules blotched with purple.
