tH. BLASTOIDEA. 
A classification based on summit openings, development of deltoids, and 
surface ornament, embracing only American spp., and rejecting names 
that end in ‘ crinus 5 : Order A. Regulares , Fam. 1. Pentremidae [sic], 
Genn. Pentremites , Cribroblastus, Saccobl., Glavaebl ., Jlesobl., Cidarobl ., 
Globobl ., Codonites \ Fam. 2. Codasieridae , Gen. Codaster: Order B. 
Irregulares , Fam. 1. Olivanidae , Gen. Olivanites ; Fam. 2. Eleuthero- 
blastidae , Gen. Eleutkerobl. ; Hambach (126) pp. 34-63. Classification 
merely follows Etheridge & Carpenter; Zittel (339) pp. 184-186. 
Carpenteroblastus veryi n. sp., Keokuk Group, Cumberland Co. Ky. ; 
Rowley in Greene (116) p. 127, pi. xxxvi. 
Cidaroblastus n. g., with genotype Pentatrematites granulatus Roem., 
incl. Granatocr. cidariformis & G. globosus Troost MS. [this is genotype 
of Granatocr ., though not of Orbitremites, and if the species is to be 
separated as a genus, the name must be Granatocrinus], diagnosed; 
Hambach (126) p. 45, pi. iii. G. parvus n. sp., St Louis group, S-W- 
Missouri, holotype in Hambach coll. ; op. cit. p. 58, pi. v : unrecog- 
nisable; Rowley in Greene (119) p. 163. 
Clavaeblastus n. g., genotype not mentioned, the genus includes all 
American spp. hitherto referred to Pentremitidea [and so far may be 
well conceived, but since it also includes the genotype of Proostocr ., 
the name must fall into the synonymy of that genus, and the Devonian 
Pentremitidea may, as the author suggests, “ necessitate the creation 
of a new genus ”], diagnosed, G. americana (Barris as Pentremitidea ), 
G. Jilosa (Whiteaves as Pentremitidea ?) inch Pentremites whitei Hall 
[which has priority], G. milwaukensis (Weller as Pentremitidea ), G. 
reinwardti (Troost as Pentremites) ; Hambach (126) p. 44. 
Codaster, rediagnosed (p. 47), G. americanus (p. 48); Hambach (126). 
G. attenuatus ; 1. c. : abnormal; Rowley in Greene (115) p. 128, 
pi. xxxvi. C. canadensis , incl. G. hindei , C. gracilis , C. kentuckyensis , 
C. pulchellus, C. pyramidatus , C. subtruncatus ; Hambach (126) p. 48. 
Codonites , rediagnosea, name preferred to prior Orophocr. because desi- 
nence in crinus is rejected (p. 46), G. campanulatus Hamb., maintained 
as full sp., G. conicus (W- & Spr.), C. fusiformis (W. & Spr.), C. gracilis 
(M. & W.), G. stelliformis (0 w. & Sh.), C. whitei (Hall) (p. 47); 
Hambach (126). 
Cribroblastus n. g., genotype not mentioned [but, since the genus includes 
the genotypes of Schizoblastus and Cryptoblastus , it must, unless further 
division be possible, fall into synonymy], diagnosed (p. 39), G. cornutus 
(M. & W. as Pentremites ) (p. 40), C. curtus (Shum. as Pentremites) 
(p. 40), C. granulosus (M. & W. as Pentremites) (p. 40, pi. y) ; Hambach 
(126). C. incisus n. sp., Lower Burlington Li mest., Burlington, la., 
holotype in Hambach coll. ; op. cit. p. 57, pi. v : syn. of Granatocr . 
projectus ; Rowley in Greene (119) p. 163. G. kirkwoodensis (Shum. 
as Elaeacr .), G. lotoblastus (White, as Granatocr .), doubtful, C. melo 
(Ow. & Sh. as Pentremites) (p. 40), C. melonoides (M. & W. as Granatocr.) 
(p. 41), G neglectus (M. & W. as Granatocr.), C. pisum (M. & W. as 
Granatocr.), C. potteri (Hamb. as Pentremites), maintained as distinct 
from G. sayi (p. 41, pi. v), C. projectus (M. & W. as var. of Pentremites 
melo) (p. 41), G. roemeri (Shum. as Pentremites), C. sampsoni (Hamb. 
as Pentremites) distinguished fr . G. roemeri (p. 41, pi. v), C. sayi (Shum. 
as Pentremites), holotype figd. (p. 42, pi. v) ; Hambach (126). G. 
schucherti n. sp., Lower Carbonif., Montana, originally included under 
Pentremites bradleyi, holotype in Smithsonian Inst. ; op. cit. p. 59,
