Material. — 1. A glass slide in the collection of the British Museum 

 (Natural History) labeled "Philomedes foveolata Bra & Norcf" at 

 one end of the slide and at the other end "Naples 1887"; a 3rd label 

 bears the number 1900-3-6-452. The slide contains a dissected 

 ostracod with parts under 6 cover slips. This slide probably contains 

 the specimen upon which Brady and Norman (1896) based their 

 description. Because of the poor condition of the slide, another 

 specimen (see paragraph 2, below) was used for the description and 

 most illustrations used in this paper. However, the appendages and 

 carapace on Brady and Norman's slide were carefully compared 

 wherever possible with those from the specimen I dissected. Both 

 specimens are almost identical, but where minor differences were 

 observed they are discussed when the appendage is described. 



2. A vial in the collection of the British Museum (Natural History) 

 containing a smaller vial with 2 whole undissected specimens in 

 alcohol. The larger vial contains the label "Pseudophilomedes 

 foveolata, Naples 1887, Norman Coll., B. M. regd. no 1911, 11.8. 

 36962-964." The specimens in this vial are designated in this paper
