STARFISHES OF THE PHILIPPINE SEAS. 385 



foregoing synopsis. Without an abundance of material it is prac- 

 tically impossible to handle this genus with any degree of precision. 

 In the specimen in question none of the plates is really tuberculate. 



In the Celebes specimen R=106 mm., r=about 18 mm., E=about 

 6 r ; breadth of ray at base, 20 mm. The largest Philippine example 

 (Port Binauga, Subig Bay) has the following measurements: R=91 

 mm., r=15 nmi., R=6 r; breadth of ray at base, 18 mm. 



In the United States National Museum collection there is a small 

 specimen bearing the number 3293 (and another number, 2100). 

 There is no locality. This specimen has R, 48 mm. and on the abac- 

 tinal surface are 25 to 27 prominent low-conical plates forming 

 tubercular eminences among the others. Although larger than Per- 

 rier's type of iV. ohtusa this example resembles it and suggests the 

 possibility that ohtusa is a young tuberculata with the tubercules a 

 little more prominent than usual.

Koehler has given a full description with figures. The Albatross 

 specimens are nearly typical. It is to be noted here that the example 

 from station 5190 has the granules, especially on the tuberosities, 

 acorn-shaped and very slightly spaced, while on the other specimen 

 the granules are flattish and closely crowded. The latter specimen 

 has R=126 mm. and on the proximal third of the ray a series of 

 papular areas have appeared between the inferomarginal and ac-
