All drawn natural size. 
The specimens of this species are short and broad, with the top of 
the lamellae arched and above the epithecal covering of the outside, 
even more pronounced than in Microcyclus. The lamellae or septa 
number about sixty (60) and are rather crowded. The central boss 
or columella of the shallow cup is strong, rounded and low, or trian- 
gular, and is formed of the upturned inner edges of the lamellae or 
septa. The cups show no other feature than those mentioned. The 
outer surface or epithecal covering is considerably wrinkled and folded. 
The base is acute and with or without radicular appendages. 
Its distinguishing characters are the shallow cup. upper 
edges of the septa arched above the otiter epithecal covering, 
shallow almost discoidal outline, short but stout coltimella 
It comes from the Upper Coal Measures of Xorthwestern 
Missouri. Specimen, figure 35, is from Weston. 
The specific name is in honor of Mr. Thomas W. Allen, of 
St. Joseph, Mo., an excellent collector in the Upper Coal Meas- 
ures of western Missouri and one to whom the author is in- 
debted for many favors. 
Leptopora ramosa, n. sp. 
Pl.\te xxviii. 
Fig. 36. — Side view of the t3'pc specimen, natural size. 
Two specimens of this peculiar coral are in the author's collection 
and both are pointed below and expand above by the multiplication 
of stems from the parent stalk, due to lateral gemmation. The coral- 
ites are more or less round, very rugose and irregular in shape. The 
cups arc very shallow and where the sides and bottoms are weathered, 
appear cellular. No septa are visible and are probably wanting, but 
placenta arc probably present as in /,. placcnla. although not seen in 
the types. 
This species occurs in the Chouteau limestone, east of Ctir- 
rvville. Mo., associated with Le])topora placenta and other cor- 
als. 
Leptopora procera, n. sp. 
PL.^TE XXVIII. 
Fig. 37- — Side view of the type specimen, natural size. 
The base of this coral differs but little from Leptopora placenta, 
being flattened and with large shallow cups and a very wrinkled and 
rugose epithecal under surface but in producing tall crowded stems
