poorly preserved, and the basal portions of three wings. Photographic 
enlargement of these wing bases shows that they fit perfectly the 
wing of the type specimen of E. dabasinskasi. It is now certain that 
the wing of this insect was petiolate, much as in Brodia. In figure 
11 the wing of the holotype of dabasinskasi is combined with that 
of the Piecko specimen to show the entire wing. As shown in the 
figure, the serrated margin extends to the base of the petiole, and 
a definite group of reticulated cross veins occurs between iA and 
CuP. 9 
The body structures of the new specimen of dabasinskasi are 
vaguely preserved, showing the general outline of the head, thorax 
and part of the abdomen (figure 12). The head and the thoracic 
segments are each 5 mm. long. 
What makes the specimen of special interest is the presence of sev- 
eral very long, filamentous structures that rest along one side of 
the abdomen and extend anteriorly to about the level of the fore 
wing (figure 13). We assumed at first that these were of plant 
origin, but two paleobotanists, Dr. Sergius Mamay of the U. S. 
Geological Survey, and Professor Elso Barghoorn of Harvard Uni- 
versity, both well acquainted with Upper Carboniferous plants, have 
expressed their convictions, after examination of the specimen, that 
the filaments were not parts of plants. As preserved, these structures 
are not carbonized but have the same surface texture, including the 
rugosity, as the brodiid integument. Similar but fewer filaments 
were associated with the megasecopterous nymph ( Mischoptera doug- 
lassi), already described from the ironstone nodules (Carpenter and 
Richardson, 1969). Furthermore, Dr. Jarmila Kukalova-Peck in- 
forms us that such filaments are associated with the specimens of 
Megasecoptera in the Upper Carboniferous shales of Commentry, 
France, and with Palaeodictyoptera which she has collected in the 
Permian deposits of Moravia. Although it is difficult to see how 
these filaments can be part of the insects concerned, judgment on this 
possibility should wait until Dr. Kukalova-Peck has published on 
the evidence obtained from the study of the European material at 
her disposal. 
Order Protodonata 
A specimen of this order was collected in an ironstone nodule by 
Mr. Joseph Makowski, of Chicago. It is of unusual interest, since 
the Protodonata have previously been represented in the Francis 
The cross veins in the rest of the wing of Eubrodia are shown in the 
photograph of the holotype (Carpenter, 1967, p. 67).
