One of these, known from only a few localities in eastern Hispaniola but better represented from the Cul de Sac Plain of Haiti, differs in no major morphological feature, other than size, from the Cuban and Bahamian populations known as Typhlops lumbricalis. The other species, un-described, appears to be restricted to the southwestern quadrant of Hispaniola. Aside from three old specimens, the hypodigm of this un-described species was obtained through the sponsorship and efforts of Albert Schwartz (ASFS designates the Albert Schwartz Field Series) and of Ernest E. Williams of the Museum of Comparative Zoology (MCZ). To Albert Schwartz I am greatly indebted for his support of my own efforts in the field and laboratory leading to the discovery of this new form. I also thank Lewis D. Ober, who generously provided some crucial specimens of T. lumbricalis (LDO designates the Lewis D. Ober private collection) and Douglas A. Ross-man for his careful critical reading of the manuscript. For the loan of specimens used in this study I wish to thank Richard G. Zweifel and George R. Foley of the American Museum of Natural History (AMNH), Edmond G. Malnate of the Acad-emy of Natural Sciences of Philadelphia (ANSP), Alice G. C. Grandison of the British Museum (Natural History) (BMNH), Neil D. Richmond and Clarence J. McCoy of the Carnegie 2— Proc. Biol. Soc. Wash., Vol. 87, 1974 (11)
