OPHIUBANS OF THE PHILIPPINE AND ADJACENT WATERS. 383 



Two specimens (Cat. No. 41216, U.S.N.M.). 



Subig Bay. 



One specimen (Cat. No. 41222, U.S.N.M.). 



Notes. The union of Ophiura sinensis with 0. kinbergi which I 

 proposed in 1905 has been accepted and confirmed by H. L. Clark, 

 who has been able to examine Lyman's type of O. sinensis, which 

 came from Australia. 



Ophiura kinbergi appears to be very widely distributed in the In- 

 dian Ocean, as well as in the western Pacific. It is known from vari- 

 ous localities in the Bay of Bengal, Ceylon, the Malabar coast, the 

 Andaman Islands, the Mergui Archipelago, the Philippines, the 

 Sunda Archipelago, and Australia. It is usually littoral, but it is 

 rather frequently met with as far as 100 meters (55 fathoms), and 

 the Siboga found it at 216 meters (118 fathoms) in 10 S. latitude 

 and 123 E. longitude. The Albatross dredged it at very similar 

 depths 208 meters (station 5398) and 232 meters (station 5420), or 

 114 and 128 fathoms.

Localities. Albatross station 5256; southern Mindanao, eastern 

 Illana Bay; Utara Point, Bongo Island, bearing N. 76 W., 5.19 

 kilometers (2.8 miles) distant (lat. 7 21' 45" N., long. 124 07' 

 15" E.) ; 289 meters (158 fathoms) ; May 22, 1908; M. 



Two specimens (Cat, Nos. 41384, 41385, U.S.N.M.). 



Albatross station 5661; Flores Sea; Cape Lassa bearing N. 21 E. r 

 23.16 kilometers (12.5 miles) distant (lat. 5 49' 40" S., long. 120 

 24' 30" E.) ; 329 meters (180 fathoms) ; December 20, 1909; hrd. 



One specimen (Cat. No. 41386, U.S.N.M.). 



Philippines. 



Two specimens (Cat. No. 41387, U.S.N.M.). 



Notes. The form of the mouth shields is slightly different from 

 that which H. L. Clark has described and figured, and the sides of 

 these shields show a rather deep notch corresponding to the bottom 

 of the genital slits. I include a photograph of the ventral surface 

 of a specimen from station 5256. 



OPHIURA MITESCENS, new species. 



Plate 81, figs. 7-9. 



Locality. Hakodate. 



One specimen (Cat. No. 41200, U.S.N.M.). 



Description. The diameter of the disk is 14 mm.; the arms are 

 broken off rather near the base, and they are only preserved for a 

 very short distance.
