 epinotidia 0-5-3 ; the back 1 cm. broad, the foot 1*2, the marginal 

 furrow continued along the side of the foot for 8-9 mm., the 

 length of the tail 4. 



The epinotidia in 2-4 series ; the inter-rhinophoriai crest very

 mandibles in front and in the middle of their length 3*5 and 4 mm. 

 The tongue 3 mm. high and long, the length of the rasp-sheath 

 4-5 mm. (its long nearly horizontal pulpy end 2 mm. long). In the
