Type material. —\\o\oXypc, USNM 328235; para- type, USNM 328236; figured specimen, NMB M9747. Occurrence. —Kccordirxg to Jackson (1922, p. 36), the holotype of Clypeaster caudatus came from float from the Gurabo Formation, or the Mao Adentro Limestone, Rio Gurabo, near Los Quemados, Domin- ican Republic. The new material is from locality NMB 16858 (Saunders, Jung, and Biju-Duval, 1986, text- figs. 15, 16) in the Rio Cana section 320 m above the base of the section near the base of the Gurabo For- mation, from beds considered to be of early Pliocene age; and localities NMB 17272, 17274 (Saunders, Jung, and Biju-Duval, 1986, text-figs. 24, 26) in the Arroyo Lopez section, beds B and D. The Yokes' material came from locality TU 1215, Gurabo Formation, Rio Gurabo, from bluff's on both sides, from the ford on the Los Quemados-Sabaneta road, upstream to ap- proximately 1 km above the ford (= Iocs. USGS 8539- 8543; Maury's Zone D), and locality TU 1444, Gurabo Formation, Rio Yaque del Norte, east bank, at Lopez, appoximately km upstream from the mouth of Arroyo Lopez, between the middle and lower hard limestone ledges. Distribution. —Clypeaster caudatus was reported by Sanchez Roig (1949) from El Jobo, near Puriales,.
