The first part of the repoii on the Echinoidea of the Albatross Philippine Expedition,1 published in 1927, dealt with the family Cidaridae. The present second part is concerned with the families Echinothuridae, Saleniidae, Arbaciidae, Aspidodiadematidae, Micropygidae, Diadematidae, Pedinidae, Temnopleuridae, Toxopneustidae, aiid Ecliinometridae.The Echinothuridae are represented in the collection by 16 species and 2 varieties, and there are in addition a couple of young specimens of Sperosoma not indentifiable with certainty as to species. The Saleniidae are represented by only one species with a variety, and the Arbaciidae by 4 species. The Aspidodiadematidae are represented by 3 species, the Micropygidae by 2, the Diadematidae by 7, the Pedinidae by 2, the Temnopleuridae by 15 (with in addition 2 unidentifiable tests), the Toxopneustidae by 2, and the EchinometridaeOf the Echinothuridae, four represent new species, one of these being the type of a new genus, Hemiphombosoma; also, there are two new varieties. These were briefly described by me in 1934.2 A new variety in the Saleniidae found in the collection was described at thesame time.There are described herein four new species, one in the Diadematidae [E'renwpyga, clebilis), one in the Pedinidae (Caenopedina annulata)\ one in the Temnopleuridae (Microcyphus excentric-us), and onein the Echinometridae (Echinostrephus formosus).
