The method of formulation proposed by Bell in his “ Attempt ’’ (G) 
is closely criticised by Carpenter (14), but the details are beyond the 
scope of the Record. 
Carpenter (12) finds that an elongated calyx resembling that of R. 
rawsoni is chiefly found in those individuals of Rhizocrinus lofotensis 
which have the arms best developed ; and, inter alia , gives some informa- 
tion as to the histological characters of Holopus , the tissues of which are 
not, as some have thought, imperfectly differentiated. 
Carpenter (13) describes as new : — 
Antedon Icevipinna (Canton), cequipinna, imparipinna , variipinna (Can- 
ton), crenulata (Borneo), acuticirra , ludovici (Hong Kong), bipartipinna 
(Hong Kong). 
Actinometra robusta (Liitken, MSS.) (Australia), grandicalyx (Canton), 
meyeri (Philippines). 
And has notes on or descriptions of — 
A ntedon carinata. 
Actinometra Solaris, parvicirra, multiradiata , bennetti. 
Antedon eschrichti, var. magellanica , Bell (7), Straits of Magellan. 
Actinometra annulata, sp. n., Bell (6), Australia. 
Antedon dentata of Say is a synonym of and has prior claims to 
A. sarsi; Veri-ill, Am. J. Sci. (3) xxiv. p. 222. 
Carpenter describes Atelecrinus balanoules and A. cubensis (Pourt.), and 
A. wy villii , sp. n. 
The name Eudiocrinus is proposed for Ophiocrinus (Semper), already 
adopted, and E. varians , E. semperi , and E. japonicus, spp. nn., are 
described. 
Carpenter (12) describes Pentacrinus blakii , sp. n., and has notes on 
P. asteria , P. muelleri , P. decor us, and on Rhizocrinus lofotensis and 
R. rawsoni. 
Antedon , sp. (Ceylon), Bell (10).

Etheridge & Carpenter (Ann. N. H. 5, ix. pp. 225-246) have found 
that what appear to be portions of the calyx-plates in Orophocrinus 
stelliformis are really the lateral portions of wide and somewhat petaloid 
ambulacra. Various points in the morphology of the Blastoidea are 
discussed.
