Found dead in shallows off a jetty on the bay side of Penzance Point. Reported to me by Annie and Jake Densmore. Approximately 120 lbs. no obvious side of death. There was a blunt force, sort of injury on the rear dorsal left side, just beyond the midpoint.

MBL Director requested that we try to locate specimens. I purchased the Pennak/Zinn paper describing the group which identified Nobska Beach as a known location from June/July 1939 and a source for the cotypes.

On Sep 20, Bill Grossman made a series of samples at Nobska Beach. He made a series of samples from high to low water at four locations running west to east more or less evenly spaced along the beach. At each location he took three to five samples from the high water mark down by 2-2.5 meter increments. Based on the paper's details he took a vertical shovelful of sand and sampled between 12-15 cm from the surface.

The resultant 16 or so jars were examined by MBLs Carsten Wolff. He found two specimens in the lowest (wettest) sample of the middle two sampling locations. He will look for additional specimens in the samples.

I thought this looked like some kind of diving beetle. Was on my stone steps in my backyard. Only standing water nearby is a small, goldfish pond I have belts it’s hundreds of meters to the Cedar swamp.

Incidental catch while dragging for squid today off Menemsha. I have heard of several sightings of this species this summer. Two of them in shallow waters. One off Chappaquoit Beach in West Falmouth. One at the Airplane House on Juniper Point. Large stingray in the shallow bight in Little Harbor. 5-6 feet across. Lengthy sightings in 3-4 feet deep mixes eel grass/sand.

I'm guessing this specimen is less than 100 lbs.
