Knrraehee. Tn 1890 Dr. Hartlaub described Dichromctra Mun- 

 zingcri from Koseir, and identified the Comatula leucomelas of 

 Riippel with the Alccto pahnata of Professor Miiller. 



Mr. Chadwick did not find Tropin,,,* in, carinala nor Dichro- 



did find the other two species known from the Red Sea. Tlctcro- 

 metra savignii and Dichromctra pahnata; the remaining four 

 species recorded include one family and three genera new to the 



Sfrphanom, Ira marginofa and Dichromctra protcctus. 



Oligorncira scrripinna is recorded from Suez Bay. where it was 

 d.vdii.-d ,M a dcplli of Id fathom., the specimens differ from the 

 type in the greater number of cirrus joints, and. in view of the 

 general constancy of the cirrus characters in this genus, may 

 eventually turn out to be a recognizable form, as may also those 

 recorded under the same name from Ceylon; correlated, as 

 usual, with the more numerous cirrus joints, the lower pinnules 

 have also more numerous joints. 



Iridometra parvicirra, discovered by the "Challenger" among 

 the Philippine Islands, is recorded from ten fathoms in Suez Bay. 

 The single specimen has a large number of cirrus joints for the 

 -onus, which, together with the furrowed first primibraeh. would 

 suggest that it was rather closer to the /. nana group of species 

 than to I. parvicirra; the former occur from Mauritius to Japan, 

 while the latter were previously known from the Philippines and 

 Japan. 



We share the author's doubt in regard to his identification of 

 Stephanometra marginata, which he records from Suez Bay, in 

 ten fathoms. 



Dichrometra protectus (under the later name in, pari pinna) 

 is given from Suez Bay, and Suakim. The number of arms m 

 the specimens is unusually small, and it would have been well 

 worth while to have recorded their size. In addition to the 

 localities cited by Mr. Chadwick, the species is known from Cebu, 

 Philippines, Fiji and Singapore. 



Dichrometra palmata was found on the coral reef at Misharif 

 Island, Khor Dongola, and from between tide marks at Suez. 



Heterometra savignii (emended, following Carpenter, to 

 savignyi) is recorded from four fathoms in Suez Bay, from nine 

 fathoms at Ul Shubuk, from ten to twelve fathoms at Khor 

 Shinab, and at the anchorage at Salaka; the distribution of 

 the species is given as "Red Sea, Ceylon," hut I am unable to 

 recall any record from the latter place ; Carpenter gives it from
