108 ANNALS NEW YORE ACADE3IY OF SCIENCES 



Wala is an American genus. IF. _pech-liaini (Coelverell) is known 

 from f Jamaica and Haiti. We have it from Montego Bay, Jamaica, and 

 Banos San Yincente, Cuba. W. vernalis (Peckham) has been reported 

 from Santiago de las Vegas, Cuba ; Jamaica ; Haiti ; San Juan and Agua- 

 dilla, Porto Eico; Vieques; fSt. Vincent and Bermuda. We took it on 

 Mona and Desecheo; and at Quebradillas, Manati, Dorodo, San Turce 

 and Naguabo, Porto Eico. We also took undetermined specimens of the 

 genus in the vicinity of Piiiar del Eio, Vihales, Cabaiias, Cristo and 

 Guantanamo, all in Cuba. 



Zygoballus and a Brazilian genus, together forming the group Zvgo- 

 ballcEe, are ximerican. It ranges from Panama northward. The only 

 record for the West Indies is suavis Peckham from Mandeville, Moneague 

 and Kingston, f Jamaica. AYe have it from Montego Bay, Jamaica. We 

 also have a specimen of the genus, marked by Peckham as a new species,, 

 from Cerro de Cabras, near Pihar del Eio, Cuba. 



DISTEIBUTION OF FAMILIES 



There are twenty-three families of Aranege now knowm in the Greater 

 Antilles. Five of these (Dictynidse, GEcobiidse, Oonopidse, Dysderidae and 

 Mimetidas) are added by this list. One family, Leptonetid^e, has three 

 species, two genera, on St. Vincent, but it has not yet been found in the 

 Greater Antilles, although it occurs on the mainland from California to 

 Brazil. It is placed by Simon between the Sicariidse and Oonopidse. It& 

 species are small, long-legged creatures for the most part cavernicolous, 

 and should be looked for in the Greater Antilles. It is fairly widespread 

 but is not yet known from southern Africa, Madagascar, Australia or the 

 southern Pacific Islands. 



There are eleven small families which are found on the mainland but 

 have not, as yet, been reported from any of the Antilles. The Atypidse 

 (p. 77) and H3'pochilid8e (p. 77) have already been mentioned. Zo- 

 dariidse is a large and widely distributed family which will probably be 

 found in the AVest Indies. Senoculidse are running spiders found only 

 on the American mainland from Mexico throughout most of South Amer- 

 ica. The Archseidae are interesting. There are three species of the type 

 genus, Archoea, known from Baltic Amber but only one living species. 

 This species is known only from Madagascar. The only other genus in 

 the family is known by two species from Patagonia. The family Pla- 

 toridse has also an interesting distribution, — two genera in South Amer- 

 ica and one in China. The remaining six families (Zoropsidae, Psech- 

 ridse, Ere'sidse, Prodidomidge, Zodariidse and Hersiliidas) have a wider 

 distribution in the Old World.
