NORTH PACIFIC OPHIURANS IN NATIONAL MUSEUM CLARK. 45 



specimens are all from the coasts of Japan, and the same is true of 

 the specimens which have long comb papillae. Moreover, many of 

 the Japanese specimens are brown rather than gray. It is remark- 

 able that in these particulars these Japanese specimens of sarsii are 

 almost exactly like many specimens from off the New England coast. 

 The large series of specimens in the Museum of Comparative Zoology 

 collection from Europe, Greenland, and the eastern coast of North 

 America, when compared with this huge series from the North Pacific, 

 seems to indicate that the northern specimens are as a rule larger, 

 duller, and with shorter comb papillae than those from near the 

 southern limit of distribution. The latter tend to have elongated 

 slender comb papillae and a brown or variegated coloration. There is 

 no hard and fast rule, however, for typical sarsii are often taken at 

 the extreme southern part of the range and occasionally at the same 

 station with the more divergent form. The specimens from stations 

 3658, 3659, 3775, 4807 4833, 4987, and 4988, and one specimen from 

 4826 and one from 4989, have elongated comb papillae. In this 

 respect they approach Jcinbergi, but the papillae are not as slender 

 as in that species, and in several other characters the specimens are 

 different.
