GRAPTOLITES OF VICTORIA. 
Associated graptolites. — M. pandas Lapworth (PI. XXII, figs. 3a, 3b), M. 
spiralis Geinitz var. permensus nov., M . scanius Tullberg (PI. XXII, fig. 4), M. 
cf dubius Suess, M. tnrriculatus Barrande, Stomatograptus australis (McCoy). 
Horizon . — Silurian, Keilor Series, near top. 
Localities . — Keilor ; Enoch’s Point, a few chains north of where the 
abandoned Darlingford-Enoch’s Point Road crosses Knowles Creek. 
Monograptus spiralis (Geinitz) var. permensus nov. 
Graptolithus spiralis, Geinitz, Neues Jahrb. f. Min., 1842, p. 700, pi. x. 
Monograptus spiralis B. subconicus, Tomquist, Siljansor. Grapt., ii, 1892, 
p. 35, pi. iii. 
M. spiralis, Elies and Wood, Mon. Brit. Grapt., Lx, Pal. Soc., lxvi, 1912, 
p. 475, text figs. 331 a, b, c, pi. xlviii. 
Polypary robust, widening from slender proximal portion persistently 
through its length ; coiled into loose spiral. Thecae on convex margin, 
12 to 14 in 10 mm. ; of uniform type ; subtriangular ; scarcely overlapping ; 
with barbed retroverted apertural region, slightly smaller and more triangular 
at proximal than at distal end. 
Fig. 7. Monograptus spiralis Geinitz var. permensus nov. a. Triangular 
and partly retroverted thecae (No. 29306). b. Distorted polvpary with usual 
fo.m of thecae (No. 29243). c. Triangular thecae (No. 29295). d. Typical 
spiral shape of polypary (No. 29253). e. Spirals (No. 29255). x4. 
Remarks .— The polypary forms an irregular spiral, never 
well displayed and seldom complete. Torsion probably accounts 
for the scalariform aspect and even for the appearance of thecae 
on the inner margin of some specimens. The varietal form 
differs from the parent species in the spacing of thecae, typical 
M. spiralis having 8 or 9 in 10 mm., its variety permensus 12 to 
14 in 10 mm. (see Elies and Wood 5). 
Associated graptolites and Horizon. — The same as for M. aplini. 
Locality. — Enoch’s Point, a few chains north of where the abandoned 
Darlingford-Enoch’s Point Road crosses Knowles Creek.
