Wliile working up the natural liistoryof Chile for inclusion m his nionograpliic 

 account of tliat country, Gay found in the Paris Museum a number of comatulids 

 which hail been labeled bj' Valenciomies Comatula picta, and wluch were said to 

 have been obtained in Chile. In the eighth volume of liis work (1854) Gay described 

 these untler Valenciennes' name of Comatula picta; but he niakes no further men- 

 tion of their occurrence m that country. The specimens belong to the common 

 Brazilian specii's of Tropiometra, and could not have come from Chile; they prob- 

 ably came to Franco on a ship from Chile which had touched at some Brazilian port 

 on the way. 



In 1857 Barrett discovered in the Sound of Skye a curious species which he 

 nameil Comatula woodwardii (Leptometra celtica), but which he renamed (jointly 

 with McAndrew) in the following year Comatula celtica, to avoid conflict with a 

 previously described fossil Comatula woodwardii. 



Dujardin and IIu])6 in 1862 published their great work on the so-called zoo- 

 phytes, the former being resj)onsible for that part which dealt with the comatulids. 

 These authors followed Midler closely, but corrected man}- of his mistakes, while 

 making some additional errors of their own. They recognized three genera of 

 recent comatulids which the}' cidled Actinomefra, Comatula, and Comaster, the 

 last being based upon Goldfuss', Comatula multiradiata and used, therefore, in the 

 same sense in wliicli it was understood by Miiller. Actinometra as described by 

 them has a centnd anus, the brachial ambulacra leading to a horseshoe-shaped 

 peripheral furrow; Comatula included the forms in w-liich the mouth is central and 

 forms the converging point of five equal radiating ambulacra on the disk. Actino- 

 metra impcrialis, which Miiller himself had shown to be but a synonvm of Comatula 

 Solaris, they reinstated as a valid species, even going so far as to consider it generically 

 different from C. Solaris.
