REPORTS ON GRAPTOLITES. 
(By T. S. Hall, M.A.) 
From San Remo, Nos. 161-173. 
The specimens, obtained from slate pebbles in jurassic conglomerate on 
the shore a little to the north-west of Griffith’s Point, San Remo, are preserved 
in a somewhat metamorphosed slate, so that their condition is not good enough 
for exact determination. They are, however, of interest from the occurrence 
of Callograptus and Ptilograptus, which have not hitherto been recognised in 
Australia. 
Diplograpt'Cts spp.—Specimens Nos. 163, 166, 168, 169, 171 contain obscure 
examples of the genus. 
Climacograptus spp.—Examples occur on Specimens 163, 170, 171 (several), 
Dicellograptus sp.—No. 172 shows an example with the habit of D. sextans. 
J. Hall, but no details are visible. 
f Dicellograptus sp.—Nos. 162, 163, and 166 contain examples of another 
small species about the same size as the previous one, but with a differently 
formed base and a pair of apertural spines. 
Dictyonema sp.—No. 167 (measured), 170 (three or four examples^at 
different levels), 173. The species has a close resemblance 
to D. delicatulum, Lapw. The occurrence of the genus is 
noticeable, as hitherto it has proved to be rare in Australia, 
except at Lancefield. Owing to its extensive range it is not of 
much stratigraphical value, and the specimens present are 
very fragmentary and badly preserved. The branches are 
nearly parallel and about '25mm. in diameter. There are 
about sixteen branches in 1cm. (40 in an inch). The con¬ 
necting bars are normal to the radiating branches, and the 
rectangular spaces are three or four times as long as wide. 
Callograptus sp.—Nos. 161 (figured), 165. In general 
appearance the fragments resemble C. salteri, J. Hall. They 
are, however, stouter than the specimens figured by Hall,* 
but not so much so as that figured by Hopkinson,f from St. 
David’s, in Wales. (See Fig. 1.)
