 Coronida bradyi Kemp, Mem. Indian Mus., Vol. 4, No. 1, p. 204, 1913, 

 and synonymy [listed only]. Gravier, Bull. Mus. Paris, 1920,

Distribution: Since Coronida bradyi was first reported by A. Milne- 

 Edwards from the Bay of St. Vincent, Cape Verde Islands, in 1869, no 

 additional material had ever been noticed in literature until 1920, when 

 Gravier described 3 specimens that had been taken by the Talisman in 

 1883, also at the Island of St. Vincent from a depth of 20 meters. He also 

 mentioned 3 other specimens in the collections of the Paris Museum, 

 which had been examined and determined by H. J. Hansen ;^^ 2 from the 

 Cape Verde Islands, and one from the island of Annobon (Anno Bom), 

 Gulf of Guinea. 



Until now, all records have been from Atlantic waters, but, as a result 

 of the Pacific explorations sponsored by Captain Hancock, the species 

 seems to be not uncommon in the Galapagos Islands where we dredged 

 it off Tagus Cove, north of Charles Island, and off James Bay, James 

 Island, in depths varying from 8 to 70 fathoms, during the month of 

 January, 1934. 



A very similar distribution is reported for the hydroid, Streptocaulus 

 pulcherrimus Allman, by Dr. C. McLean Eraser in "Distribution of the 

 Hydroids in the Collections of the Allan Hancock Expeditions. '"^^ This 

 animal, which was originally described from the Cape Verde Islands, was 

 discovered by Dr. Eraser in the vicinity of both Hood and Barrington 

 Islands in the Galapagos. 



Size: All of the specimens are small, some indeed very small, yet 

 the largest, a female measuring 46 mm. in median length exclusive of the 

 rostral plate and spines on the posterior border of the telson, carapace 8, 

 rostrum about 2.1 mm., is considerably larger than the largest Talisman 

 specimen recorded by Gravier, which measured 31 mm. over all, "ante- 

 rior margin of rostrum to posterior extremity of telson." This is the speci- 

 men upon which Milne-Edwards' original description was based.
