Duct of spermatheca quite long, being one-half times shorter, and flat as in 

 A. panthera. Vagina short and oviduct only moderately long. Uterus large, 

 long, and composed as in Limicolaria of a large sack of translucent membrane 

 filled with closely fitting, leaf-shaped saccules. Albuminiparous gland three 

 sided, columellar, edge keel shaped and coming to a blunt point. Ovotestis 

 short, granulose and bound tightly to the albuminiparous gland. 



Length of penis, 10 mm.; of vagina, 7 mm.; of oviduct, 11 mm.; of sper- 

 matheca, 23.5 mm. 



Remarks. — Euaethiops differs anatomically from Limicolaria 

 in the following points: a larger, thicker albuminiparous gland; 

 a shorter hermaphroditic duct smoother above but heavily 

 granulose at its entrance into the spermoviduct instead of con- 

 sisting of a long series of granulations as in Limicolaria; a 

 large uterus; a wider, flatter and shorter spermatheca; a longer, 

 more twisted vas deferens; a larger penis; and a much shorter, 

 thicker penial retractor. 



The shell differs in having a more elongate aperture, nearly 

 one-half the total length of the shell. The columella bends far 

 backward instead of being almost straight and is truncate as 

 in Achatina. The lip is marginate and expanded backward at 

 the base. 



While the anatomy of Euaethiops resembles that of Limicolaria 

 in the possession of a penial retractor, its radula is closest to 

 the type found in Achatina. The shell has a truncate columella 

 which serves to place it closer to the latter genus. Thus this 

 new form fails to fit into any of the previously described genera. 



In the recently erected genus Limicolariopsis there is a species 

 known as L. kivuensis Preston which bears a superficial resem- 

 blance to E, loveridgei in that it has a slightly reflected lip. 

 The columella is, however, not truncate. In addition it has a 

 sculptured embryonic whorl as in other species of Limicolariopsis. 

 The aperture is likewise typical in being smaller and more ovate, 

 and the whorls more numerous as in Limicolariopsis. A dis- 

 section of Limicolariopsis kempi Prest. shows that this genus is 

 anatomically the same as Limicolaria. However, the anatomy 

 of L. kivuensis resembles that of E. loveridgei in having a rather 

 similar type of penis, but in all other respects, penial retractor, 

 ovotestis, etc., it is entirely identical with Limicolariopsis and 

 Limicolaria. It is uncertain just what the true status of L. 

 kivuensis is, whether it is a case of convergence or an inter-
