are greatly elongated. Gislen has pointed out that in Bell's figure of the arm base 

 while the pinnules are on the left side they are on brachials corresponding to PI, P 2 , 

 and so on. P c is not shown, and it is somewhat uncertain whether the lowest pinnule 

 should be interpreted as P ft or Pj. 



In 1908 I pom ted out that in Professor Bell's description of E. granulatus he uses 

 "first" and "second" pinnule in the sense of the two first pinnules on the same side of 

 the arm, whereas Professor Semper used the same terms strictly, taking the pinnules 

 first on one side of the arm and then on the other hi their actual sequence considering 

 the arm as a whole. Thus Professor Bell found a greater difference between the 

 "first" and '"second" pinnules in his E. granulatus than Professor Semper did in his E. 

 indivisus, although in reality such a difference is nonexistent. 



I examined the type specimen of E. granidatus at the British Museum in 1910. 

 It is a large specimen, the arms measuring between 85 and 90 mm. in length. There 

 are 18-20 cirrus segments. I could see no difference whatever between this specimen 

 and others undoubtedly referable to E. indivisus from the Philippines that I had 

 examined. 



The characters of the type specimen from Bohol were given by Professor Semper 

 as follows: The centrodorsal is small and flat, 2 mm. in diameter, with the cirri ar- 

 ranged in a single marginal row. The cirri are XVI, 18-20, 9 mm. long, and very 

 knobby, especially proximally where the expansion is equal to the length of the 

 segment. The first two segments are short, as long as broad, and the third-sixth are 

 the longest, twice as long as broad. The outermost segments are slightly compressed 

 laterally and smooth. The last bears, in addition to the terminal claw, a strong tooth 

 (that is, opposing spine). The five arms are 80 mm. long. The IBr series appear to 

 arise directly from the centrodorsal; the two elements are united by syzygy and the 

 IBr 2 bears a pinnule. The following ossicle (first brachial) is without a pinnule. The 

 second brachial bears a pinnule, and the third and fourth are united by syzygy, the 

 fourth bearing a pinnule. The brachials are almost twice as broad as long, and in the 

 middle of the arm are very obliquely wedge-shaped. The two first pinnules are 

 small, but rather stout basally, and the third and fourth are the longest, 8 mm. long. 

 Then follow shorter pinnules, and subsequently pinnules which gradually become longer 

 and at the same time slenderer. The disk was lacking in the only specimen secured. 

 The pinnules are blotched with light and dark yellow brown, and the dorsal surface 

 of the arms is marked with two parallel zigzag lines. 



Dr. P. H. Carpenter's redescription of Professor Semper's type specimen is as 

 follows: The centrodorsal is small, convex, bearing cirri in two marginal rows, the 

 dorsal pole being free from them. The cirri are about XX, about 20, 9 mm. long. 

 The third segment is about as long as broad, or a trifle longer than broad. The fifth 

 segment is the longest, and those following are nearly all longer than broad, and 

 overlap on the dorsal side. The penultimate bears an opposing spine. The radials 

 are partially visible, and are about one-third the length of the syzygial pair formed by 

 the elements of the IBr series. The IBr 2 bears a pinnule on the left side. The five 

 arms are 75 mm. long. The first brachial (third ossicle beyond the centrodorsal) is 

 short and oblong and bears no pinnule. The next four or five brachials are nearly 

 oblong, slightly shorter on one side than on the other, the longer side being shorter 

 than the width and bearing a pinnule. The eighth and following brachials have
