Coll- Tola' 1895/8; Dr. Graf det." (2) One bottle with white label 

 marked: 'Thilomedes sp. 9; Rotes Meer: Stat. 90; CoU. Tola' 1895/8; 

 Dr. Graf det." This bottle contained one vial with 2 females con- 

 taining eggs that had not yet been extruded into the brood chamber 

 and with a label that had been marked "PMlomedes sp. 9 (A)." 



Smce Dr. Graf had not designated a holotype of Philomedes polae 

 Graf, Dr. Pretzmann suggested that I select a lectotype from the type 

 material. Examining the material, I found 2 specimens in the first 

 bottle that I could equate with Philomedes polae Graf, using primarily 

 as a basis for identification the distinctive secondary appendage 

 described and figured for this species by Graf (1931, p. 37, fig. 5i). 

 The third specimen in the first bottle I identify as EupMlomedes 

 arostratus Kornicker, recently described for the fii-st time from the 

 Maldive Islands, Indian Ocean. 



The 2 specimens in the second bottle I equate to specimens 

 described by Graf (1931) as Philomedes species on his page 38 and 

 illustrated in his figure 6. The similarity of the distribution of 

 primary and secondary claws on the caudal rami of the specimens at 

 hand with the pubhshed description of Philomedes species makes it 

 certain that this identification is correct. After studying these speci- 

 mens, I have concluded that they are females of Philomedes polae Graf. 



I acknowledge with thanks the assistance of Dr. Gerhard Pretzmann 

 in obtaining specimens for study from the Naturhistorisches Museum, 

 Vienna, Austria, and of Miss Caroline Bartlett, who inked the final 

 illustrations. I would hke also to thank Mr. I. G. Sohn and Doctors 

 Raymond B. Manning and W. Duane Hope for reviewing the manu- 

 script.
