(Skeat Expedition, 1899-1900.) By F. F. L a i d l a w , B.A. Cantab., Assistant Lecturer and Demonstrator in the Owens College.1 [Received March 19, 1903.] 2 (Plate XXIII. & Text-figures 50-56.) The collection described below was made entirely by Mr. Evans on the shores of a small islet called Pulau Bidan, a few miles north of Penang. It proves a most interesting one, and includes, so far as I can discover, only one previously known species, Thyscinozoon auropunctatum Coll. As in describing Mr. Gardiner's collection from the Maldives W , I have to note the scarcity or absence of the Euryleptidse, represented doubtfully only by a much damaged fragment in Mr. Evans's series. The only previous record of species from the shores of the Malay Peninsula that I have been able to discover was made by Collingwood, who described and figured the following species from Singapore:- Thysanozoon allmani. Proceros hancockianus. ,, buskii. Sphyngiceps Icicteus. Grouping these specimens with those of the Skeat Collection and adding Pseucloceros bedfordii from Singapore, kindly given me by Mr. Lanchester, we get the following list classified according to Lang's system [6] :- Acotylea.
