The radula is when compared with the size of the animal large, about 2 3 

 m.m. long, and somewhat more than one m.m. broad ; it is composed of about 

 90 transverse rows, with 67 teeth in each of them. The central is much 

 smaller than the adjoining laterals, with a long arched cusp. The laterals 

 somewhat rapidly decrease in size after the 14th ; on the outermost the 

 basal plate gradually disappears, while the breadth of the teeth exceeds 

 their length. 



The genital organs are more complicated than in Trachia. The female 

 portion has at its origin a rather short, thick mascular coecal appendage, which 

 most probably represents the amatorial gland ; it is widened near its origin 

 and at its rounded end. The seminal receptacle is a round bag, attached 

 to a long thin peduncle of about the same length as the uterus. The seminal 

 duct is moderately long, but the penis comparatively thick and attached by 

 a stronsr muscle. 



Fam. Bulimidse. 



BuLiMUS. — Subg. AmpJiidromus, 



The only two species which I found among the coco-palms were Buli- 

 mus atricallosus, Gould, and B. interricptus, var. citrinus ; the uniform 

 colom-ed greenish yellow variety. The former is the more common species. 



Besides these two, the ubiquitous ^tenogyra gracilis is by no means 

 rare at the roots of palm trees.
