This is a characteristic species of the west coast of tropical America from Lower 
California to northern Peru. The records for Timor and Celebes are undoubtedly mistakes. 
The largest specimens have R =125 mm.; R=about 9r. The color in life is probably red 
of some shade, but there is no published statement on this important point. Many speci- 
mens, not always the largest, have the bifasciate arrangement of the series of papular 
areas on the base of the rays, but this seems to be a matter of individual diversity and not 
correlated with age or locality. It may be well to state here that the supposed ‘‘Pha- 
taria” on which Miss Monks based her paper, “Variability and Autotomy of Phataria”’ 
(1904) is, as already pointed out by Fisher, Linckia columbie. 
BUNASTER. 
Déderlein. 1896. Jena Denks., 8, p. 317. 
Genotype: Bunaster ritteri Déderlein, 1896, I. c. Monotypic. 
The curious little sea-stars composing this genus are as yet too rare to permit any 
discussion of their affinities to be either reliable or profitable. Only 3 specimens have been 
taken and each of these seems to represent a distinct species, one of them being described 
below for the first time. The 3 supposed species are distinguishable from each other as 
follows: 
Key to the Species of Bunaster. 
Abactinal plates on basal half of rays in 3 irregular series; actinolateral plates in 2 series proximally: 
No pedicellarie; “ball and socket’’ plates present; subambulacral spines not nearly twice as long as

Bunaster ritteri. 
Déderlein. 1896. Jena Denks., 8, p. 317, pl. xxii, figs. 1-lg. 
The only known specimen of this species was taken at Amboina by Semon. It is 
very small, R only 10 mm., but rather stout, the disk being 4 mm. high and the rays 2.6 
mm. wide. The color is variegated red-brown, dusky brown, and milk-white. 
Bunaster lithodes. 
W. K. Fisher. 1917. Proc. Biol. Soc. Wash., 30, p. 91—1919. Bull. 100 U.S. Nat. Mus., p. 398; pl. 95, figs. 
8-8); pl. 124, fig. 4. 
A relatively large species with R =22mm. The rays are short and stout. The papule 
are often in groups of 2 to 4 (usually 3), but they are well spaced and do not form well 
defined areas. The color is variegated brown and buff of several different shades. The only 
known specimen was taken on Apo Reef, Mindoro Strait, Philippine Islands, by Dr. L. E. 
Griffin, December 24, 1911, and is now in the Museum of Comparative Zodlogy. 
Bunaster uniserialis ! sp. nov. 
(Plate 7, Figure 2; Plate 36, Figures 5-7.) 
R=11 mm.;r=2.3 mm., br=2.8 mm., R =4.8r but only 4br. In the living specimen 
R=12 mm.,r and br, each 3 mm., hence R =4r or br. Abactinal surface quite flat; vertical 
diameter of disk and arms at base, not quite 2mm. Rays (in dry specimen) quadrangular 
in cross-section, the sides being vertical, very slightly tapering, until close to tip, blunt; 
1 Uniserialis =in a single series, in reference to the abactinal plates on the ray.
