A. H. CLARK : THE CRINOIDS OF THE INDI.^N OCEAN. 147 



? India. — Five small and medium- sized specimens. 



Other Records. — Fiji ; Zamboanga ; Cebu ; Philippine Islands ; Ovalau ; 

 Mortlock Island, Carolines ; New Caledonia; Java; Johore Strait, Pulau Ubin : 

 Bougainville Island ; New Guinea ; Salawatti : Nam-Zit Island ; Amboina ; Tonga ; 

 Blanche Bay, New Britain; Poulo Condor, Cochin China ; Hong Kong; Singa- 

 pore; Batjan: Andaman Islands; Ramesvaram, Gulf of Manaar ; f'eylon ; Red 

 Sea ; Suez Bay ; Suakim Harbour. 



Depth. — Littoral, and down to 12 (? 36) fathoms. 



Remarks. — An examination of the type of Carpenter's Antedon brevicu- 

 rieato, preserved at Leyden, of the type of hXa Antedon cequipinna preserved at 

 Hamburg, and of the type of his Antedon conjungens , preserved in the British 

 Museum, shows that they are identical with Liitken's Antedon protectus. Chad- 

 wick's Antedon ohelli was founded on small specimens of this sjiecies. 



The specimen of Comatida palmata recorded by Miiller f rom Zamboanga, which 

 was collected by M. Hombron on the famous expedition of the " Astrolabe," is in 

 reality an example of this species, as I discovered upon examining it at the Paris 

 Museum. 



DICHROMETRA LAEVICIRRA. 



Antedon laevicirm 1881. P. H. Carpenter, Notes from the Leyden Museum, 



vol. 3, p. 189. 



Habitat. — Aru Islands. 



Remarks. — In the type at Leyden the cirri are XXII, 24, 24, 25, 28 ; there 

 are thirty-seven arms ; the rays and division series are entirely free laterally, 

 though close together ; the dorsal pole of the centrodorsal is flat and rather 

 broad. The eighth-eleventh cirrus segments are very slightly longer than broad ; 

 the last ten to twelve are rather sharply carinate, in dorsal view showing a 

 dorsoventrally elongate tubercle. The proximal pinnules resemble those of the 

 slender pinnuled form of D. protectus ; the second and third segments of the 

 lower pinnules are slightly carinate. The pinnules on the outer side of the 

 outer arms of each distichium are, as in D. protectus, considerably larger than 

 those on the inner side, and on the inner arms. The division series of this 

 species resemble those of D. protectus ; in fact the whole animal is so much like 

 the slender pinnuled form of D. lyrotectns that it would not be surprising if they 

 should turn out to be in reality the same thing. 



DICHROMETRA SIMILIS. 



Antedon sirnilis 1888. P. H. Carpenter, " Challenger " Reports, vol. 26, Zoology, 

 p. 235, pi. xlvii, figs. 1-3. 



Locality. — Near Kandavu, Fiji. 



Depth. — ? 



Remarks. — There is very little difference between this species and D. pro- 

 tectus, and I am inclined to believe that they will turn out to be identical. Bell's
