Toroucu the courtesy of Prof. Herdman of Liverpool and Dr. W. T. 
Calman of the British Museum, I have been entrusted with a few examples 
of “sea-spiders ” collected on the east coast of Africa by Mr. Cyril Crossland. 
They prove to belong to undescribed species of the widespread genera

The localities from which these specimens were obtained lie to the north 
and east of the district surveyed by Prof. Stanley Gardiner, whose collection 
of Pyenogonida I have recently (1907) described. The present short contri- 
bution may be regarded as supplementing, to some extent, the account of 
Prof. Gardiner’s collection, and I use here the same terminology as in that
