scorpius and Palaeophonus become also in aspect integral elements of the 
eurvpterid waterlime fauna. 
7 As Eusarcus and the Siluric scorpions are so much alike in their 
body form, they may be assumed to have had similar habits, and it 
follows that these scorpions were probably also given to burying them- 
selves in the mud, waiting there for their prey as undoubtedly many of 
the eurypterids, and especially Eusarcus, did. In this connection the 
fact becomes extremely significant that Palaeophonus nuncius 
was blind, according to Thorell and Lindstrom’s observations, and 
that, for this reason, Lindstrém [1855, p. 8] infers some difference 
in habits from those of the recent scorpions,' and believes that it may 
have possessed a burrowing mode of existence. 
It would be singular indeed if, of all the Suiluric terrestrial fauna, 
the scorpions alone should have been repeatedly carried out to sea in a 
good state of preservation; much more plausible is the assumption of 
their coexistence in the sea with the similarly constructed and closely 
related eurypterids, with which their remains are found associated. 
The genus Hastimima White 
David White has described [1909, p. 589] under the name Hasti- 
mima whitei certain fragmentary remains from the Carbonic plant 
beds ot Santa Catherina, Brazil, as doubtful plants, but under protest, as it 
were, after various paleontologists had failed to recognize them as belonging 
to any other group. Seward [1909, p. 484] has referred a similar frag- 
ment from the Witteberg series of South Africa to Hastimima, suggesting 
that it represents part of a body segment of aneurypterid. This suggestion 
was fully verified by Henry Woodward after inspection of the specimen. 
This pioneer and leader among the investigators of eurypterids, has also 
subjected White’s photographs of the Brazilian types to critical notice
