a marked difference between the oral (anterior) and anal (posterior) group 
of arms, these last being, to a certain but very variable degree, devoid of 
tentacles, ambulacral grooves, and sub-epithelial (nervous) band (but not 
of the ambulacral aquiferous tube). The author further dwells on tho 
difference of the ** rosette ’’ (transformed basals) in Antedoii Acti- 
nometra, and between Comaster and Solanocrinus. 
On Holopus and its relation to Cyathidium, vide the note of 0. W. Thom- 
son (25). In this author’s “Atlantic” are figured Pentacrinus maclearanus^ 
sp. n. (ii. p. 124) (400 faths., off Brazil) (living unattached ?), Hyo- 
crinus hethellianus (ib. pp. 96-99), and Bathycrinus aldrichianus (p. 93). 
Ilycrinus (g. n.) carpenteri (sp. n.), Koren & Danielssen (10), (1050- 
1495 faths., 63° 22' to 65° 55' lat. N. and 0° 36' lat. E. to 7° 20' lat. W.), 
will probably also include the last-named generically ; it has a long 
stem, articulated almost as in Rhhocrinus, but without cirri, divide! dis- 
tally into branching roots, calyx not supported upon dilated stem-joints, 
composed of five coalesced small basalia, and fifteen (3 X 5) radialia, those 
of the inferior circle coalesced, arms ten, not branched, syzygia with short 
intervals along the arms, pinnnlsB about eleven on each side, first pinnula 
on the eleventh brachial segment, sexual products in the inferior pinnulcc, 
mouth and oral ring covered by five oral plates, anal tube inter-radial, &c.
