INTEODUCTION. 



The miscellaneous assembly of new Arachnids described 

 in this paper are all in the Albany Museum, except when 

 otherwise stated. Perhaps the most noteworthy are the small 

 marine spiders taken by the Rev. N. Abraham at Muizenberg-, 

 near Cape Town (Muizenbergia abrahami and Erigo- 

 n op sis littoral is), a discovery of some interest seeing that 

 previously only one marine genus, viz., Desis, had been 

 known from South Africa. Whether their occurrence on our 

 coast has any special zoo-geographical importance it is impos- 

 sible to decide at present, as little or nothing is known of the 

 Arachnid fauna of other shores ; in any case it seems very 

 probable that quite a new field awaits exploration on the coasts 

 of the southern hemisphere, in worm-tubes and similar habitats 

 between tide-marks. 



Some of the descriptions are based on material which has 

 been kindly lent to me by the authorities of the British 

 Museum, London, and of the Natal Museum, Pietermaritzburg; 

 for this courtesy I am especially indebted to Mr. A. S. Hirst, 

 the Arachnologist of the British Museum, and to Dr. E. 

 Warren, the Director of the Natal Museum.
