and o feet in de})th. Tlie male spiders were in one of tlie lower corners 

 of this common web."' There were about 1,000 spiders in this we)) and 

 several other smaller ones had about 300 spiders in each. Of the re- 

 maining American species of Uloboriis. one is confined to California, 

 nine to Mexico and Central America and fourteen to South America. 



MIAGRAMMOPIXJE 



Miagrammopes is known from Africa, Madagascar, southern Asia 

 and Australia. It has two species in Mexico, one in Guatemala and four 

 in northern South America. Banks recorded the genus from Haiti on 

 the basis of an immature specimen which could not be placed in a given 

 species. He also described cuhanus from Cavamas, Cuba. The remain- 

 ing species is scoparius Simon, which is recorded only from St. Vincent 

 but which we took near Arecibo, Porto Eico, and on Desecheo. In both 

 these places it was among shrubs and low trees. This genus belongs to 

 a subfamily which contains but one other genus (Hi/ptiotes) and it is 

 northern in its distribution, being known only in Europe and America 

 north of Mexico except, possibly, for one species from Ceylon. 



DlCTYXID^E 



This family is represented by about a hundred species on the American 

 mainland but seems not to have been re])orted from the "West Indies. 

 We took an undetermined species of Dictyna at Guane, Cuba. This 

 genus is found in Europe and the Mediterranean region, northern and 

 central Asia, Japan, the Philippines and from the extreme northern to 

 the extreme southern parts of America. In x\nierica it is rather northern 

 in its distribution, twenty-two species being known north of Mexico as 

 compared with thirteen in South America. 



QECOBIID.E 



This family contains but one genus, (Ecobius. It is known from the 

 Azores, Canaries, the Mediterranean region, Arabia, Japan, N'ew Cale- 

 donia and America. Three of the five American species are apparently 

 confined to South America ; one to Florida : and the fifth, parietalis 

 (Hentz), is recorded by Petrunkevitch from Massachusetts, Florida, 

 f Alabama and Lower California. Simon makes this species a synonym 

 of navus Bl. and records it from the Atlantic islands, Japan, 'New Cale- 

 donia, Venezuela, southern United States and the Antilles. I do not 

 know the basis of the last locality. He says it is undoubtedly carried 

 by commerce. We took it under the loose bark of a stump on the coastal
