Localities. — Colombo Breakwater, Ceylon. — Fourteen specimens. 



Port Blair, Andaman Idands. — One fine specimen with forty arms; the 

 proximal pinnules are much larger and stouter than usual. 



Andaman Islands.— Twelve specimens, most of them with thirty, a few witli 

 forty, arms. This series exhibits great variation in the size of the proximal 

 pinnules ; so much difference is there between the two extremes that, were it 

 not for the intergrades, they would certamly be considered as representing differ- 

 ent species. A rather large specimen with thirty arms 90 mm. long represents 

 the condition in which the cirri and lower pinnules are remarkably small and 

 weak, tlie latter especially being unusually slender, with very little difference 

 between those on the outside and on the inside of the rays, so that it might 

 almost be taken for a specimen of D. tenera. A forty-armed example, on the 

 other hand, has remarkably large and stout lower pinnules with the difference 

 between those on the inside and the outside of the arms exceptionally pro- 

 nounced. Most of the specimens are quite typical and agree with a very large 

 series at hand from Singapore, the Philippine Islands, and other places in the 

 East Indies.
