Rupert Jones! gave it the name of Leava leidy?, and described two 
varieties, one Z. letdyi var. Williamsoniana, from Ardwick, near 
Manchester, and the other Z. leidyi var. Salteriana, from Cottage 
Row, Crail, Fifeshire. The present example agrees fairly closely 
with the Fifeshire specimen; but, on the whole, it seems best to 
create a new species for it, Zeava trigonoides, sp. noy., rather than 
risk confusion by adding a varietal appellation. 
Specimen 2, from Shipley, is of interest, owing to the great difficulty 
of its interpretation. Possibly the best explanation is that it is the 
glabellar region of a Prestwichia. The presence o: two minute 
erescentic dots, one on each side of the median line, is in favour of 
this theory, on the assumption that they are the larval eyes of the 
animal. Dr. Henry Woodward, however, who has examined this 
specimen, is very doubtful as to its limuloid origin. 
Specimen 8, from the Kilburn Coal, Trowell Colliery, Notts. The 
curious feature in this specimen is the presence of crescentic openings 
on each segment similar to the ‘stigmata’ found in scorpions and 
other Arachnids, suggesting that it may be a fragment of an air- 
breathing animal. 
Specimen 4, from Shipley, is probably one of the first abdominal 
segments of Hoscorpius sp., two specimens of which genus have been 
found in this district—one from near Chesterfield, and another, at 
present undescribed, found by the author in the Digby Claypit, 
Kimberley, Notts. 
Specimen 5, from Brindsley, Notts, is a single segment of «an 
Arthropod, and possibly referable to Hurypterus. 
Specimen 6, from Shipley, is the wing of an insect probably belonging 
to the order Paleeodictyoptera of Scudder. 
Specimens 7 and 8, also from Shipley, are a fragment of a much 
smaller insect’s wing, which, in its incomplete state, would be 
impossible to assign to any definite order. 
Insects’ wings are very uncommon in the Coal-measures of this 
district, only one having been found near Chesterfield, and described 
by 8S. H. Scudder? under the name Archeoptilus ingens.
