32 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 6 1 



1. Cebu Reefs; "Challenger." — -One specimen; I cannot see any 

 way in which it differs from true protectits. 



2. " Challenger " Station No. 174. — One specimen with thirty 

 arms ; none of the cirrus segments are quite so long as broad. 



3. " Challenger" Station No. 174. — Three specimens. 



4. Ramesvaram, Gulf of Manaar. — Two small specimens. 



5. Blanche Bay, Nczv Britain.—- One specimen. 



6. Fiji. — One specimen. 



7. Tonga. — One typical specimen. 



8. Andaman Islands. — One specimen. 



9. Edge of Reef off Nam-Zit Island.- — One specimen. 

 Remarks. — I cannot see that the type of Carpenter's Antedon 



similis presents any valid characters by which it may be separated 

 from the earlier Antedon protectus. 



It also appears to be the same thing as Bell's Antedon moorei, 

 though the type of the latter is a young and immature individual 

 with the dorsal processes on the outer cirrus segments a trifle more 

 conspicuous. 



The type of Antedon similis is regularly thirty armed, and is in 

 every way stouter than the type of Antedon moorei; the cirrus seg- 

 ments are never quite so long as broad, while the earlier are longer 

 than broad in moorei. 



The pinnules of the type of Antedon similis resemble those of 

 certain varieties of Protectus.

i. Thursday Island; 3-4 fathoms.- — One specimen; the cirri ar 

 XXXV, 24-29 (usually 28), 20 mm. to 25 mm. long; from the 

 eleventh onward the segments are strongly carinate dorsally or are 

 supplied with broadly rounded dorsal spines. The arms are forty- 

 one in number (four being broken off), 80 mm. long. P, is the 

 longest, but slender, similar to P x but longer ; P 3 is slender and weak, 

 not nearly so long as P x ; the basal segments of these earlier pinnules 

 are more or less carinate. 



2. Port Essington, Coburg Peninsula, Northern Territory of 

 South Australia. — One specimen. 



3. North of Cape Hillsboro' ; H. M. S. " Rattlesnake."— One
