STAEFISIIES OF THE PHILIPPINE SEAS. 331 



with 2 spines. In small specimens there are usually 4 or sometimes 5 

 (as in A. sarissa). In the adults I find scars of 4 or 5. 



An example from station 5520 has small forcipiform pedicellariae, 

 such as are figured by Sladen (1889, plate 54, fig. 6), scattered 

 thickly over the abactinal and proximal superomarginal plates, with 

 a few on the outer end of the proximal inferomarginals. A large 

 specimen from station 5212 (No. 6 of the foregoing table) has the 

 abactinal pedicellariae less numerous and of a bivalved form, the 

 jaws being truncate, as wide as high, or wider than high. A speci- 

 men from station 5394 has rather more numerous abactinal pedicel- 

 lariae of the same form, while another from 5395 has pedicellariae 

 of the forceps shape with shorter jaws than the figure of Sladen, 

 together with others which might be classed as bivalved with trun- 

 cate jaws higher than wide. In this specimen the pedicellariae are 

 intermediate between the two extremes. 



In the example from station 5394, above referred to, the pedicel- 

 lariae on the actinal intermediate plates adjacent to the adambulac- 

 rals are unlike Sladen 's figure 7, but are of the typical bivalved type, 

 being quite similar to the pedicellariae of Hippasteria. The jaws 

 are truncate and sometimes twice as wide as high. A few are scat- 

 tered over the rest of the interradial area. The example from sta- 

 tion 5520, which has the very numerous abactinal forcipiform pedi- 

 cellariae, has the actinal intermediate pedicellariae smaller and 

 either bivalved or of the type figured by Sladen ; or with spatulate, 

 rounded jaws intermediate between the two. Specimen No. 6 from 

 station 5212 has a very few actinal intermediate bivalved pedicel- 

 lariae, a short conical tubercle occupying its place on the other plates. 

 A specimen from station 3595 has the tubercles more prominent, and 

 present on plates near the margin, as well. 



I have been able to compare Anthenoides peircei directly with 

 cristatus. The actinal pedicellariae of peircei are bivalved, but low, 

 resembling those of Oreaster. The difference is not of generic im- 

 portance, however. If the jaws were a little higher the pedicellariae 

 would be like those of cristatus from station 5394. In my key to the 

 Goniasteridae (1911 d^ p. 173) I relied on the form of the pedicel- 

 lariae and the presence of abactinal and superomarginal granules to 

 separate Leptogonaster from Anthenoides. Anthenoides, it appears, 

 has rudimentary dorsal granules, which, with the variations of 

 Leptogonaster cristatus, bridge the small gap between the two genera. 

 The enlarged group should therefore be known by the older name 

 Anthenoides, which includes also Antheniaster Verrill. Sladen was 

 in doubt as to the validity of his genus, as he recognized its close 

 affinity to Anthenoides. His conclusion that Leptogonaster was dis- 

 tinct was justified, because Perrier described the dorsal skeleton of
