size than any of the specimens examined by M. de Loriol. I have 

 found small Lamellibranchs and an entire Hoplodactyla in the 

 stomach. I do not remember to have seen any previous mention 

 of Asteroids feeding upon Holothurians. 



Distribution. Previously known from Penang. 



The specimens appear to agree in all essential details with the 

 original description : the general facies is, however, somewhat 

 different, the arms, which are six in number in all individuals seen 

 (about 30), being longer and narrower in the Malacca form. As 

 M. de Loriol had received as many as fourteen specimens from 

 Penang, this difference seems to be in some way correlated with 

 the locality. 



The large pedicellariae on the adambulacrals mentioned by 

 de Loriol as present in some cases appear to be constant in our 

 specimens, and the anatomical details are subject to very little 

 variation. Contrary to the general rule in long-armed starfish, 

 the arms had not undergone regeneration in any of the specimens. 



It is a striking fact that this species was not met with at 

 Singapore, where an apparently similar habitat is available.

At Professor Bell's request, M. de Loriol kindly sent two of his 

 original dried specimens for comparison : these were much smaller 

 than the average of our examples, but they seem to be similar in 

 all essential respects, although, on account of the condition of 

 M. de Loriol's specimens, it was impossible to carry out a very 

 detailed investigation.

• Locality. A single large 7-armed specimen from between tide- 

 marks, Singapore. The arms had undergone a considerable amount 

 of fracture and regeneration.
