MONOGRAPH OF THE EXISTING CRINOIDS. 639 



SCAI.PELLUM, SP. 

 PI. 53, fig. 1345. 

 Specimens of Stylotnetra spinifcra taken by the Albatross off Habana, Cuba, 

 in 76 to 157 fathoms, carry barnacles of this genus on the cirri. 



Scalpellum is very seklom seen on the cirri of the comatulids, though it is not 

 at all unusual to find it on Stylomctra. 



Family VERRUCIDiE. 



VEERUCA NITIDA HOEK. 



Figs. 1249, 1250, pi. 39. 



Verruca nitida was found on pentacrinites of different genera dredged by the 



Challenger off the Meangis Islands in 500 fathoms. The pentacrinites taken here 



were Metacrinus costatus^ M. moselei/i, M. varkins, M . wi/vilUi, M. fmurrayi, 



Endoxocrinus alterniciri^us and Uypalocrmiis naresianus. 



VERRtrCA, SP. 



P. H. Carpenter states that in one of the two specimens of Metacrinus cingu- 

 latus taken bj^ the C hallenger off the Kei Islands in 140 fathoms the place of one of 

 the cirrus sockets is occupied by a group of barnacles of this genus. 



\'ERRUCA, SP. 



A specimen of Meta/irinus nobilis taken by the Challenger off the Kei Islands 

 in 140 fathoms showed a large Verintca covering the whole of one side of a nodal, 

 and also extending onto the columnals above and below it. 



\'ERUUCA, SP. 



Carpenter records several examples of a species of this genus from a specimen 

 of Metac-rinus intemiptus taken by the Challenger in lat. 10° 14' N., long. 123° 

 54' E., at a depth of 95 fathoms. They were attached to the cirri. 



Family BALANID^. 



PACHYLASMA CRINOIDOPHILUM PILSBRY. 



Figs. 1246-1248, pi. 39. 



This form was found on the column of a species of Metacrinus dredged by the 

 Albatross in 103 to 152 fathoms in the Eastern Sea, off Kagoshima Gulf. 



OBSCrKR LARVAL CIRRIPEDE. 



P. H. Carpenter states that he found an obscure larval cirripede attached by 

 its ventral margin to a cirrus of a specimen of Metacrinus varians which was 

 dredged by the Challenger in 500 fathoms off the Meangis Islands.
