Photo. 2.—A portion of the British Museum specimen, showing several seeds. A pinnule: 
of Sphenopteris obtusiloba is‘also seen. Nat. size. 
Photo. 3.—A. portion of the Glasgow ‘specimen, showing numerous well-preserved seeds: 
and portions of the rachis-like structures. The apical lobes of several of the seeds: 
are clearly seen. X 4. . 
Photo. 4.—A. portion of the{Glasgow specimen, showing some well-preserved seeds. A 
multilobed foliar structure, possibly of the nature of a “cupule,” is seen in the neigh-- 
bourhood of one of the seeds, near theftop of the:photograph. x 4.

(Drawings 1—4 and 6_by{Mr. J. Allen ; drawings 5 and 7—11 by Miss G. M. 
Woodward.) | 
Fie. 1.—Lagenostoma Kidstoni.—A seed from the Glasgow specimen, showing five of the: 
apical lobes. X 8. 
Fig. 2.—L. Kidstoni.—A seed from the Glasgow specimen, showing the hilum. 5. 
Fia. 3.—L. Kidstont.—A. seed from the Glasgow specimen, showing six apical lobes. The: 
integument, represented by a carbonaceous layer, is only preserved in the upper 
portion of the seed.  & 5. 
Fic. 4—L. Kidstont.—The basal portion of a seed from the Glasgow specimen. In the 
neighbourhood of the seed a sheath-like body, possibly of the nature of a “cupule,” 
and divided into a numberfof teeth at the apex, is somewhat indistinctly seen. The: 
same body is also seen in Plate 1, photo. 4. X 3. 
Fie. 5.—L. Kidstont.—Several seeds, apparently in continuity with an axis. The integu- 
ment of the seeds is only partly preserved. From the British Museum specimen.

Fic. 6.—L. Kidstoni.—Highly magnified cells of the integument of a seed shown on the 
' Glasgow specimen. X about 70. ; 
Fig. 7.—L. Sinclairit.— A. hight) branched axis, the branches being terminated by seeds,. 
in most cases enclosed in a “cupule.” Kidston Coll. No. 3530. Nat. size. 
Fic. 8.—L. Sinclairi.—An enlarged drawing of two seeds enclosed in their “ cupules,” and 
borne on a branched axis. Kidston?Coll. No. 3531. x 5. 
Fia. 9.—L. Sinclair?.—An enlarged drawing of a seed without its “ cupule,” showing the- 
flutings at the apex. Kidston Coll. No. 3530. x 5. 
Fig. 10.—Z. Stinclavri.—A number of seeds, most of which are enclosed in “cupules,” and 
attached to the finer branches of a compound frond with reduced lamina. The ribbed 
nature of the “cupule” is clearly seen. Kidston Coll. No. 3529. Nat. size. 
Fie. 11.—L. Sinclairt.—Two seeds enclosed in their “‘cupules,” of which an enlarged: 
drawing is shown in fig. 8. Kidston Coll. No. 3531. Nat. size.
