this suite of material he named three new species, one of which was 

 from an unknown locality. Between 1900 and the present, additional 

 material has accumulated, but, aside from occasional large series 

 from specific localities, the accretion has been gradual; material from 

 the Lesser Antilles has been especially slow in reaching collections. 



The field work of the senior author has taken him to all islands 

 whence Monophyllus has been reported although he has not in every 

 case secured specimens. In his Antillean endeavors, Schwartz has 

 had the assistance of Ronald F. Klinikowski, David C. Leber, and 

 Richard Thomas; all have made collections of Monophyllus that 

 have interest and value. The junior author spent six weeks on Dom- 

 inica in 1966 under the auspices of the Bredin-Archbold-Smithsonian 

 Biological Survey of Dominica and secured the first recent series of 

 Monophyllus from any of the Lesser Antillean islands. 



Eight names are currently associated with the genus Monophyllus 

 Leach, as follows: M. redmani Leach, 1821 (type-species); M. por- 

 toricensis Miller, 1900; M. plethodon Miller, 1900; M. clinedaphus 

 Miller, 1900; M. cubanus Miller, 1902; M. luciae Miller, 1902; M. 

 frater Anthony, 1917; M. ferreus Miller, 1918. Of these, all but M. c. 

 cubanus and M. c. ferreus are regarded as full species; M. frater is 

 known only from fossil fragments and M. clinedaphus is known 

 from a single specimen of unknown provenance. The ranges of the 

 species, as presently understood, are: M. redmani, Jamaica; M. 

 portoricensis , Puerto Rico; M. plethodon, Barbados; M. cubanus 

 cubanus, Cuba; M. c. ferreus, Hispaniola; M. luciae, St. Lucia; M. 

 frater, Puerto Rico, fossil ; M. clinedaphus, unknown. 



Both of us have collected specimens of Monophyllus on the Lesser 

 Antillean island of Dominica. In borrowing specimens from various 

 collections, we have inadvertently discovered unreported Monophyllus 

 from several other Lesser Antillean islands. Although it was not our 

 intent to examine all specimens of Monophyllus presently available, 

 we have been able to to study a total of 139 specimens from throughout 

 the West Indies. Abbreviations used in the present paper to denote 

 collections in which Monophyllus are housed are: AMNH (American 

 Museum of Natural History) ; AS (Albert Schwartz collection) ; 

 BMNH (British Museum, Natural History, London) ; KU (Museum 

 of Natural History, University of Kansas) ; MCZ (Museum of Com- 

 parative Zoology, Harvard University) ; RMNH (Rijksmuseum van 

 Natuurlijke Historie, Leiden); USNM (United States National 

 Museum). For the loan of material we are grateful to Karl F. Koop- 

 man, John E. Hill, Miss Barbara Lawrence, A. M. Husson, and Charles 

 O. Handley, Jr. The senior author also wishes to acknowledge the gift 

 of specimens of Cuban Monophyllus from Gilberto Silva Taboada.
