hairs with the centre darker coloured and cellular. The cells 

 not arranged in regular longitudinal series. (PI. VII., 

 fig. 48.) 



592. HAIR OF MOLE (Talpa Europaa). These hairs 

 are evidently flattened, the margins indented on one side. 

 The centre occupied by transverse irregular cells, which 

 are opaque from the enclosed air. 



593. HAIR OF RABBIT (Lepus cuniculus}. Larger hairs, 

 with three or more longitudinal rows of cells, almost to 

 the margin of the hair. Small hairs with one row of cells, 

 similar but distinct from Mouse hair. 



594. HAIR OF WEASEL (Mustela vulgaris). Two-thirds 

 of the diameter of the larger hairs cellular; a single line 

 of short cells running down the centre. In the smaller 

 hairs the cells are longer, and the clear space between 

 them greater. 



595. HAIR OF MOUSE (Mus mtisculus). The larger 

 hairs exhibit three longitudinal series of cells, which occupy 

 three-fourths of the diameter of the hair. Indistinct 

 markings, representing the margins of the external scales, 

 are just visible. 



596. HAIR OF BROWN RAT (Mus decumanus). Trans- 

 lucent; central cells shallow, passing across more than 

 three-fourths of the diameter of the larger hairs, with short 

 connecting branches to the cells above and below. 



597. HAIR OF LESSER HORSESHOE BAT (Rhinolophus 

 hipposideros). Transparent; scales cylindrical, expanding 

 upwards, with nearly straight or slightly waved edges. 

 No cellular portion visible in any of the Bat hairs included 

 here. 



598. HAIR OF BARBASTELLE (Barbastcllus communis). 

 The margin finely serrated; scales wholly or partly 

 cylindrical, conspicuously short and close. 



599. HAIR OF LONG-EARED BAT (Plecotus aunt us). 

 Flattened, with a deeply notched outline ; serratures oppo- 

 site or alternate; scales half embracing the shaft, darkened 

 at the margin, faintly striate. (PI. VII., fig. 43.) 



600. HAIR OF WHISKERED BAT ( Vespertilio mystacinus}.
