Scalpellum wyethi is a very large barnacle. Several specimens were growing on the submarine cable and this part of the cable has not been raised since it was laid in 1903.

JUDD Department of Zoology, McMaster University, Hamilton, Ontario. IN HIS ACCOUNT of the reptiles occurring in the vicinity of Hamilton, Ontario, Brown (1) reports that the snapping turtle is "com- mon in the Bay, marsh, and a secluded pond near LaSalle Park" and records the capture of a specimen with a carapace eight inches long. During the summers of 1946 and 1948 the writer made measurements of ten snap- ping turtles captured in the Dundas Marsh at Hamilton and these are recorded in Table 1. ^ Received for publication August 25, 1950. The measurements were made with a rule graduated to tenths of an inch and represent horizontal lengths rather than lengths follow- ing the contours of the shells. Turtle No. 10 was captured on July 16, 1946 floating at the surface of the water in a lethargic condition.
