Oome little time back Dr. L. Schultze very kindly placed in my hands for description, a small 

 collection of Pycnogonids from Angra Pequena (Lüderitzbucht) and the adjacent coast of Africa. It has 

 been a matter of considerable regret that my engagements have delayed their examination much loriger 

 than I anticipated. The collection, if small, is an extremely interesting one containing three new species, 

 for one of which a new genus has been instituted. It is perhaps unfortunate that several specimens are 

 immature, a fact which renders their specific designation more difficult and uncertain. 



The Pycnogonida have not received much attention on the African coasts but it is not unlikely that 

 the Fishery Investigations carried on up to quite rec«ntly by the Cape Government may have produced 

 some interesting discoveries in connection with this group of animals as has occurred with others. 



As far as I have been able to ascertain the following list contains all the species hitherto recorded 

 from Africa south of the Equator. Those occurring in this collection being marked with an asterisk.

The majority of these were taken during the "Valdivia"-Expedition and are not littoral forms. 



Ammothea cuspidata. 



Specific characters: 



Body discoid, lateral processes close together and armed distally with branched spines. A mid 

 dorsal row of these also occur. Similar spines occur on the cheliferi and legs. No auxiliary claws. 



Body robust, discoid, due to the varying length of the lateral processes which are quite close 

 together and armed distally with branched spines. Of these the posterior one is much the largest. Cephalon 

 broad, expanded, but the interval between it and the first pair of lateral processes is reduced to a minimum. 

 The ocular tubercle lies in the middle of the cephalon and is a straight but stout structure bearing four
