ORDER LITINIA 



in the posterior portion of the cavity of each of a strongly staining body, which 

 may be assumed to be protoplasmic. The bottoms of the amphids are strongly 

 cutinized. Oesophagus conoid, finally about half as wide as the base of the 

 neck; just where it joins the intestine it appears to expand suddenly, although 

 Ittl (4) or ^ s ex P ans i n could hardly be called a bulb. It is possible that 



this expansion indicates the presence of glands about the base 

 w of the oesophagus. The intestine becomes at once three-fourths 

 as wide as the body and in cross-section appears to present only 

 two cells. Little that is definite is known concerning the lateral 

 fields, but it is presumed that they are well-developed. The 

 median fields are rather distinct. They contain a series of cells, 



I at any rate in the neck; these cells are about half as long as the 

 neck is wide and are separated from each other by distances 

 about twice as great as their length. Tail of the male at first 

 conoid, then cylindroid in the posterior half, where it is about 

 one-fourth as wide as at the base. The spinneret has a very 

 minute pore. The caudal glands lie in front of the anus. A 

 straight refractive piece appears to subtend the arc of the spicula. 

 These latter are barely cephalated by an almost imperceptible expansion and a 

 previous constriction. Immediately behind the anus there are two or three 

 minute submedian setae; similarly, close to the anus, and in front, there is a pair 

 of subventral setae, all seen with considerable difficulty. The balance of evi- 

 dence is in favor of the existence of two testes. 



Habitat: Algae and sand at their bases, in surf, Island off Port Royal, Jamaica.

 The mouth is a simple, unarmed, conoid depression 

 on the ventral side of the head a little behind the 

 anterior extremity. There are no distinct lips, but 

 the anterior extremity is modified so as to resemble 

 a lip-region; it is set off by a minute constriction 

 and presents a minute depression that takes acid- 

 carmine stain more strongly than do the adjacent 



parts. No doubt this terminal "cap" serves some distinct function, as tactile 

 or gustatory. The conoid oesophagus finally becomes almost three-fourths as 

 wide as the base of the neck. There does not appear to be any distinct cardia. 

 Around the base of the oesophagus there is a circlet of small cells which stain 

 in the same manner as do the cells of the intestine. This latter becomes at 

 once about three-fourths as wide as the body. The lateral fields have not been 

 distinctly seen. Nothing definite is known about the renette and excretory pore. 

 Tail conoid to the simple terminus, which is set off by a broad, shallow con- 

 striction. The caudal glands appear to be located in front of the anus, probably 

 a long distance in front of it. In the male the anus is slightly raised. Spicula
