to a new genus, intermediate between Leanira and Psammolyce, and there- 

 fore may be called Euleanira. 



Euleanira Ehlersi ') nov. gen. n. sp. 



One of the three specimens has a length of about 15 mm., and the 

 number of its segments amounts to 65. The head is rounded, nearly as 

 long as broad, provided with two pairs of semilunar eyes, situated closely 

 behind its frontal border; the anterior of them are somewhat larger than 

 the posterior ones. Between the eyes the 

 tentacle arises with a short basal joint, pro- 

 vided with two small auriculate ctenidia; its 

 distal part measures about one and a half the 

 length of the head. The buccal segment bears 

 two tentacular cirri, the dorsal of which is 

 a third longer than the tentacle, whereas the 

 ventral is a third shorter than the dorsal one. 

 At the innerside of the basal part of the 

 tentacular cirri a short, digitiform appendage 

 is situated, that presumably represents the 

 lateral antenna. The palps are long and slender,

smooth, tapering distally, about three or four times longer than the tentacular- 

 cirri. The scales have a rounded trapezoidal shape, with a sinuated external 

 border and the scar of attachment lying in the centre ; they are translucent, 

 whereas a broad, semilunar, brown-red spot consisting of large polygonal cells 

 occurs on their internal half. A typical foot (fig. 1) consists of a large, 

 cylindrical neuropodium, provided with a rounded anterior and posterior lip ; 

 the first-named is somewhat narrower than the last one. Between them a 

 fascicle of setae emerges, that consist of a long, smooth shaft and a
