Fishei — New Starfishes from the Philippines and Celebes. 91 



Bunaster lithodes, new species. 



Diagnosis. — Very close to B. ritteri Doderlein in general appearance, 

 but differing in lacking the curious ball-and-socket granules of that form, 

 and in having abundant, low, bivalved pedicellariae on the papular 

 areas, and a few narrow tongs-shaped pedicellariae on the abactinal 

 plates; outer actinal intermediate plates larger than the inner, and sub- 

 am bulacral spines slightly narrower; granules between the naked areas 

 of plates smaller and more numerous. R=22 mm., r=5 mm., R=4.4 r; 

 breadth of ray at base, 6 mm. 



Type. — No. 2498, Museum of Comparative Zoology. 



Type locality. — Apo Reef, Mindoro Strait, Philippines. 



Asterina cristata euerces, new subspecies. 



Diagnosis. — Very close to typical A. cristata Fisher but differing in 

 having abactinal, spiniform pedicellariae, only 12 to 14 swollen abactinal 

 plates to a ray, 8 furrow spines, and S or 9 marginal mouth spines. 

 R=20 mm., r=9 mm., R=2.2 r; breadth of ray at base, 10 mm. 



Type.— Cat. No. 37,036, U. S. N. M. 



Type locality. — Ulugan Bay (near mouth of Baheli River), Palawan 

 Island, 2 to 5 feet, mud, sand, sea-weeds. 



Henricia microplax, new species. 



Diagnosis. — Rays 5. R=45 mm., r=7 mm., R=6.4r; breadth of ray 

 at base, 8 mm. Rays slender, depressed, slightly swollen at base; disk 

 small with an interradial sulcus near margin. General appearance of 

 abactinal surface similar to that of H. sanguinolenta ; superomarginal 

 plates forming an inconspicuous series ; inferomarginals in a regular con- 

 spicuous series ; 3 or 4 series of actinal intermediate plates at base of ray ; 

 adambulacral spines about 15, besides 3 or 4 on the furrow face of plate. 



Type.— Cat. No. 37,006, U. S. N. M. 



Type locality. — "Albatross" station 5518, Mindanao Sea, off Point 

 Tagolo, Mindanao, 200 fathoms, gray mud, globigernia, bottom tempera- 

 ture 54° Fahr. 



Henricia arcystata, new species. 



Diagnosis. — Similar in general appearance to H. mutans (Koehler), 

 but with shorter rays, 2 or 3 spinelets on the furrow face of the adambu- 

 lacral plates ( instead of apparently 1 ) , and with a distinct series of T-shaped 

 inferomarginals and crescentric superomarginals. R=72 mm., r=l0 mm., 

 R=7.2 r; breadth of ray at base, 9 to 10 mm. Rays slender, depressed, 

 curved at the end, tapering very slightly. 



Type.— Cat. No. 37,007. U. S. N. M. 



Type locality. — "Albatross " station 5536, between Negros and Siquijor, 

 278 fathoms, green mud, bottom temperature 53.5° Fahr.
