Schmidt (W. HE.)  Cryphaeus in dem Siegener Schichten. 
Zeitschr. d. Deutsch, Geol. Ges., vol. 59, 1907. 
The author describes as Cryphaeus attavus a species with a head and a short, tri- 
angular pygidium, which shows a faint development of four pairs of marginal lap- 
pets, seen best by the four pairs of pits within the doublure. 
Dr. Clarke in his paper on Devonic of Parana, p. 156, remarks: ‘This, certainly, is 
not a Cryphaeus, even phylogenetically, for exceedingly young forms of Cryphaeus 
have sufhciently demonstrated that the ontogeny presents no four-spined stage. The 
tail is similar in the character of its lappets to those obscure structures in Proboloides 
pessulus, a new genus created by Clarke in the same work.

Geol. Mag., Decade 5, vol. 6, No. 11, 1909, p. 482. 
The author refers the [Hastimima JWheitei to the genus Eurypterus, p. 485, as part 
of a body segment of that genus. 
This paper is followed on p. 486 with a note on the genus Hastimima from Brazil 
and the Cape, by Henry Woodward, in which the author compares it with Eurypterus 
punctatus Salter.
