Zool.— Vol. I.] BANKS— MEXICAN ARACHNIDA. 207 



Regarding the Cape fauna in particular, one will at once 

 notice the occurrence of certain spiders of a truly tropical 

 appearance. Such are Artema allanta, a Pholcid found in 

 houses throughout tropical America; Heteropoda venatoria, 

 a large species common in the tropics of both hemispheres; 

 species of Selenops; an Hersilid; two species of Caponidas, 

 curious two-eyed spiders; an Oonopid; several species of 

 Epeiridee, as Cyrtophora fusiformis, Argiope argentata, 

 and Gasteracantha hexacantha ; and various species in other 

 families. One species, Nephila hasselti, was previously 

 known only from the eastern part of Asia. 



Of the peculiarities of this Cape fauna, one may call at- 

 tention to the abundance of species of Litkyphantes and of 

 Habrocestum, while the true Theridiums are not numerous, 

 and there are no species of Philodromus. The Drassids 

 are very numerous in species, though quite rare in speci- 

 mens. One interesting feature of the collection was the 

 large number of specimens of the curious Solpugids and 

 certain Phrynidas. These are so rare in collections that 

 such an abundance of material fills one with wonder. 



I have been able to identify but few species with those 

 described by the Rev. O. P. Cambridge in the " Biologia 

 Centrali-Americana." His spiders for the most part seem 

 to come from quite different regions. Prof. Peckham has 

 recently published a large paper on Central American At- 

 tidae; but few of these are represented in this collection. 



Altogether there are 315 species, 298 of which are true 

 spiders, classed in 28 families. The Epeirida? leads with a 

 total of 50 species; then follow the The i " : .xida?, Attida?, and 

 Lycosidae. Seven families are represented with but one 

 species. The types of new species are in the Academy. 



Of the localities referred to the following are in the Cape 

 Region of Baja California: Sierra San Lazaro, Sierra 

 Laguna, Sierra San Nicolas, Agua Caliente, San Fran- 

 cisquito, Coral de Piedras, San Jose del Cabo, La Chupa- 

 rosa, El Taste, La Palmilla, Las Palmas, Pescadero. 



The following places are in Baja California north of the 

 Cape Region: San Julio, Ensenada, Calmilla Mines, Santa 

 Margarita Island, San Quintin, Magdalena Island.
