Corallimorphus. In tlie "Supploineiit" Ilertwif'- ('88) jidded to this 

 genus, as aiiothoi" iiieinber of tlui lainily, the genus Cori/nactts. Pre- 

 vious to tliis, liowever, Andres ('83) liad defined the family Cory- 

 nactidiv, splitting up Gosse's family Capneadse, which he had previously 

 accepted ('80^*), though recognizing that it was not altogether natural, 

 and agreed witli Ilertwig in incorporating in his newfamily the genera 

 Cotynacils and (Joi'allimorphHs, adding also the genus Capnca. The 

 name proposed by Andres is preferable to that of Ilertwig, both ou 

 accountof the gr(%at(M' aiiticiuity of the genus, which serves as its sponsor, 

 as well as on acc'ount of llertwig's name carrying with it a signilicance 

 which might give rise to misuiulerstanding. Hertwig's name has, how- 

 ever, the priority in publication, and it is tlierefore; proper to retain it. 



Oe.niis CORALLIMORPHUS, MoHeley. 



Corallimorphidie, with capitate tentacles, there l>eing only one inter- 

 mediate tentacle in each radial series; some of the marginal tentacles 

 have no intermediate tentacles (;orresponding to them.

 Two specinieiiH. 



Tliese two specimens I lound in a Ixrttle which contained also S])eci- 

 mens of Mi/<>iiaittJii(s (diihii/iiKs and Paractis viiiosa. IJotli wer«^ in a 

 very poor state of i^reservaiion, so tiiat 1 can luld nothing to the ana- 

 tomical descrii>tion given l)y Hertwig ('82). One of the specimens 

 wasattachedtoM IVagmentof a giisterojxxl shell. Thc^'ohimn measured 

 l'"' in height and the disk had !i diameter of 2..")"". There were no 

 indications of any tendency to infold tli<' margin, iind sections demon- 

 strated the absen<'e of ;iiiy sphincter. 



The marginal tentacles Avere forty-eight in number, twelve being de- 

 cidedly larger tlian tln^ other thirty-six, and there were twelve inter- 

 mediate tentacles (M)rresponding to the larger marginal ones. The 

 cai)itate natureof the tentacles could be made out only with difficulty, 

 but they certainly i)ossessed that cliaracter. There appeared to ]>e a 

 slight thickening of the disc mesoghea at the base of each of the inter- 

 mediate tentacles. 



Family DISCOSOMID^E. 



SticliodiU'tylime witli tentacles of only one form, short and tentacular, 

 and (covering the greater portion of the surface of the disc. Sphincter 

 muscle strong and circumscribed, not embedded in the mesoghea.
