be differentiated by specific differences in the number and arrangement of these grooves 

 (Moore, 193 1 a). The pellets from WS 144 have five grooves in common with N. tenuis 

 (Mont.) and N. moorei, Winckworth, which are shown in transverse section in Fig. 

 I c, d for comparison. The grooves are fairly, but not extremely, deeply cut, and in this

Notes on abundance and size 

 of pellets 



A few large and some smaller ovoid 

 type present. Diam. 0-55 mm., 

 length 0-95 mm., length/breadth 

 I -75 ; smaller sizes down to 

 0-25 mm. long. 



No pellets found. 



A very few ovoid type present. 

 Diam. o-i2mm., length 0-26 mm., 

 length/breadth 2-2. 



Ovoid type abundant, but no 

 count made. A single specimen 

 found of a rod-shaped type with 

 one longitudinal groove. 



No pellets found. 



Ovoid type abundant, but no 

 count made. 



Only a few ovoid type present, but 

 plain and sculptured rods abun- 

 dant. Ovoids, diam. 0-28 mm., 

 length 0-46 mm., length/breadth 

 1-64; plain rods, diam. 0-12 mm.; 

 sculptured rods, diam. 0-26 mm.

No pellets found. 



A few large ovoid type, and a few 

 smooth rods. Rods diam. 0-05- 

 0-15 mm., and in lengths of 3 or 

 4 times the diam. 



A lot of ovoid type present, but so 

 broken that the count might easily 

 represent i/io only of the true 

 number. Lengths up to 0-5 mm. 



A few large ovoid type present. 

 Diam. 0-24 mm., length 0-47 mm., 

 length/breadth 1-95. 



No pellets found. 



they resemble those of N. moorei. But the ridges are all of about the same size, and the 

 mid-ventral ridge is very prominent, as in A*", tenuis. It does not belong therefore to 

 either of these species, and if it does belong to a Nucitla it probably belongs to one whose 

 pellets have not yet been described.
