with 2 or 3 jaws similar in form to those of the adambiilacral phites, 

 but only about two-thirds as long, and a trifle stouter. In the Misaki 

 specimen the inferomarginal pedicellariae are fewer and only about 

 half or less than half the' length of the larger adambulacral pedi- 

 cellariae. 



The si3ecimen from the Tawi Tawi Islands is young (R equaling 36 

 mm.), but more typical in appearance. The paxillae are quadrate, 

 close-set, and there are 3 adambulacral spines, followed by a large 

 pedicellaria, which, however, belongs to the actinal intermediate 

 plate. This pedicellaria is not present beyond tlie middle of ray. 

 Inferomarginal spines, generally 2. 



The Palawan specimens differ, therefore, from typical L. maculata 

 in having smaller, roundish paxillae with fewer spinelets, and in hav- 

 ing prominent fiuperotnarginal pedicellariae. Specimens from numer- 

 ous Philippine localities must be examined before the status of these 

 vai'iations can be satisfactorily deteimined.

A .small seven-iayed specimen is referred to this species. There 

 is little doubt that it lepresents true L. savigniji, although there are 

 as yet no adambulacral pedicellariae. R=27 mm., r=5 mm. Adam- 

 bid a era 1 spines 3, or sometimes 4. there being a spine out of line 

 (adorally) between the second and third spines. The abactinal 

 spines are very stout. Koehler (1910r/, p. 10) gives excellent critical 

 and descriptive notes, and a photographic figure of the abactinal 

 surface of a specimen from the Andaman Islands and of another 

 from ^fauritius.
