Mr, Fowler, of Eingwood, has been good enough to send me, 

 for examination, the whole of his extensive collection of Emydia 

 crihrum. The majority of the specimens are from the Eingwood 

 locality, and others are from the New Forest. Although it 

 might possibly be a difficult matter to say from which locality 

 individuals came if all the examples had been mixed together, 

 the two series as arranged show certain differences. The most 

 striking feature of the New Forest contingent appears to be the 

 generally clearer ground colour ; whilst among the Eingwood speci- 

 mens there is a tendency to fuscous suffusion, chiefly in the males, 

 and to greater prominence of the transverse bands and the longi- 

 tudinal streaks in both sexes (figs. 2 and d 3" ^ )■ Fig. 6 represents 

 a suft'used male specimen, but this is not the darkest in the series. 

 In five female examples and one male from the New Forest, and 

 in three females from Eingwood, the transverse markings are 

 only faintly indicated (fig. 5 ? ). Most of the female specimens 

 from the last-named locality are strongly marked (fig. 4), but two 

 examples have the spots rather small (fig. 7). In the large 

 proportion of the specimens, the transverse markings referred to 

 as bands are series of more or less confluent spots, but in several 

 examples the sub-basal, ante-medial, and post-medial bands are
