DERBYSHIRE CAVES 255 
pottery occurred in a similar cavity. The upper cave-earth yielded several 
artifacts of flint, including a fine battered-back knife from the Font Robert 
level, tools of limestone, and pieces of worked bone and reindeer antler. 
Fish scales and portions of a large egg, probably duck, occurred in the 
same level, also pot boilers of stone and fragments of charcoal around 
a possible, but not well-defined, hearth. 
Tools of quartzite, crystalline stalagmite and limestone, similar to 
specimens previously found, have occurred in each of the three Mousterian 
levels. ‘Two finds of special interest have been made in the 12-ft. layer, 
Mousterian (2) in age. The first of these is a bone tool 2 in. long, roughly 
triangular i in form, with a base } in. wide, cut into the form of two prongs, 
each 1 in. long. The second appears to be a bone “‘ bull roarer.”’ It is 
34 in. long, % in. wide, and of pointed oval form, perforated near one end 
and having an extreme thickness of about # in. 
In comparison with other portions of the cave, animal remains have 
been less numerous, and no additions have been made to the fauna already 
recorded. During the spring a number of flies were collected, infested 
with fungi. These I submitted to Mr. T. Petch, F.R.M.S., who has 
kindly supplied the accompanying report, from which it will be observed 
that the specimens include new species of fungi and others of special interest. 
A report by Dr. J. W. Jackson, on the remains of small mammals, etc., 
collected, is also attached. 
I anticipate that the excavation will be completed early in the coming 
autumn, and I propose to leave an entire cross-section of the deposit exposed 
to view. This will form the most complete and representative stratified 
section of the Upper and Lower Palzolithic cave deposits of Britain, and 
it is earnestly hoped the Committee will take the necessary steps to preserve 
it intact as a British type section, adequately protected against unauthorised 
interference. 
Future Work.—An unexpected opportunity has presented itself for the 
immediate excavation of the Boat House Cave, on the southern side of the 
gorge and at its eastern extremity, through the draining of the lake which 
has hitherto occupied the bed of the gorge and prevented any examination 
of this cave. 
It will be necessary to undertake the work without undue delay. A trial 
section has yielded promising indications and proved that the deposits are 
entirely undisturbed. 
I propose, subject to the sanction of the Duke of Portland, to commence 
this work immediately upon the completion of the Pin Hole excavations. 
REPORT ON FUNGI OCCURRING ON FLIES COLLECTED IN THE PIN HOLE CAVE. 
By T. Petcu, B.A., B.Sc. 
Five species of fungi have been identified on the flies collected by 
Mr. Leslie Armstrong in Pin Hole Cave. These are: 
(1) Hirsutella, new species, parasitic on Blepharoptera. 
(2) Stilbella Kervillet (Quel.) Lingelsh., parasitic on the Hirsutella. 
(3) Spicaria (Isaria) farinosa (Holms) Fr., parasitic on gnats. 
(4) Sporotrichum Isarie Petch, parasitic on Spicaria (Isaria) farinosa. 
(5) Beauveria Bassiana (Bals.) Vuill., parasitic on a fly. 
Hirsutella sp. nov.—This fungus first forms discontinuous brown patches 
of mycelium on the body of the insect, and subsequently, erect fuscous 
clave, up to 8 mm. long and 0-2 mm. diameter. In this condition the 
fungus is fertile and identifiable. 
Very frequently, however, the Hirsutella develops into long hair-like
