Genus: STOMOLOPHUS L. Agassiz 

 Stomolophus meleagris L. Agassiz 



See Plate 10, Volume IV 



Material examined : One large specimen, taken in Conway 

 Bay, Galapagos Archipelago, July 28, 1931, by the "Alva." 



Remarks : This specimen, an unusually fine one, the bell (pre- 

 served specimen) having a maximum horizontal diameter of 

 280 millimeters and a vertical diameter of 120 millimeters, the 

 length of the manubrium being 140 millimeters, is of exceptional 

 interest since it is the first record of the adult species from the 

 Galapagos Archipelago, from which locality Haeckel described 

 the younger stage of the species as Brachiolophics collaris Haeckel 

 (1880), the few other West Coast of America records being re- 

 stricted to the mainland, ranging from San Diego, California, 

 (Bigelow, 1914) , where Dr. Henry B. Bigelow recorded the Prus- 

 sian blue colour variety of Stomolophus meleagris as abundant 

 during August and September, 1913, and the Pacific Coast of 

 Costa Rica from which Haeckel (1880) described it as S. agaricus 

 and the Bay of Panama specimens described as S. chuni Vanhoffen 

 (1910). 



This species is much better known from the many records on 

 the East Coast of the United States, from inside the Chesapeake 

 Bay, off Tangier Island and southward to the Capes (Boone) and 

 more especially from the Atlantic Coast off the Virginia Capes, 

 on the coast of North Carolina, down to South Carolina (type 

 locality) , also at Charleston (Mayer) , the beach of Warsaw Island,
