ON SOME PYCNOGONIDS FROM THE SEA AROUND KII PENINSULA

Abstract

The Pycnogonida occurring around the coast of Kii Peninsula have been scarcely examined. So far as I am aware, only two species, Lecythorhynchus hilgendorfi and Ammothea (Ammothella) bi-unguiculata, both found living commensally with sea-cucumbers, have ever been reported by 0HSHIMA (1927 a, b) from Seto. Very recently, HEDGPETH (1949) recorded eight species collected by the Albatross Expedition in 1900 and 1906 from deep waters of Kii area. The present account is based upon a small collection deposited in the museum of the Seta Marine Biological Laboratory. The great majority were secured by Mr. S. SAKAGUCHI from bottom materials dredged at 100 to 200 meters depth off Minabe, not far from the Laboratory, but a few of the specimens were collected by myself and other members of the Laboratory in the neighborhood of Seta, where the Laboratory is located (UTINOMI, 1950).
