156 HIND : DEXDROID GRAPTOLITES IX CARBONIFEROUS ROCKS. 
that this is not the case. 'Bars' may be present in all the Den- 
droids, I tliink, but they are particularly regularly developed 
in Dictyonema itself. The fashion of growth is a far more dis- 
tinctive and rehable character." 
Lately I had the opportunity of showing the specimens 
to Dr. H. Lapworth, F.G.S., and he unhesitatingly pronounced 
them to be Dendroid Graptolites. 
Under these circumstances T think the figures and brief 
descriptions of the specimens should be published. 
Callograptus Carboxiferus, sp. nov. Fig. 1, PI. XVIII. 
Specific characters. — Frond branching from a single acute 
base, obscurely fan-shaped. Branches narrow and linear, 
dividing dichotomously, united by occasional dissepiments, 
forming a retiform network, with large elongate meshes. 
Locality. — Pendleside series, Hook Clough, 60-70 yards 
up stream from the old road at the back of Hook Cliff farm 
house. 
Observations. — The fauna associated with this Graptolite 
was : — 
Prolecanitcs compressus. 
Stroboceras sulcatus. 
Solenomya costellatus. 
Ceratiocaris, sp. 
Productus cf. semireticulatus. 
Desnograptus Monensis, sp. nov. Fig. 2, PI. XVIII. 
Specifix^ characters. — Frond narrow and elongate. Branches 
dividing dichotomously, joined by tew transverse dissepiments, 
forming a small open diamond-shaped network. 
Locality. — Pendleside series, Poolvash, Isle of Man, from 
black shale interbedded with lenticles and hummocks of lime- 
stone, containing marine fossils, in the first hollow between 
tide marks, west of the barn at Poolvash farm. 
Observations. — The network is more regular and meshes 
not so elongate, nor is the frond as fan-shaped as is the case 
with Callograptus carbonijerus.
