' Doubtfully distinct from U. turtoni. It is not quite so rhomboid as that species, 

 which is also found in Algiers, but I have seen much intermediate material which 

 liints at a connection of the two. 



-The magnificent work in which this species with other Unioues was figured was 

 never finished, and no descriptions of the Naiades were written. The beautiful col- 

 ored figures are wonderfully characteristic and are accompanied by names. 



■'Credited to Parreyss in catalogue. 



■•This is quite likely only a variety of the preceding, but seems to be thinner and 

 is more evenly elliptical. Von Martens believes it to be the same as Lea's mosulensis.
