round a clear space which I take to be a oontraotile vesicle, though I saw 

 no contraction. The stomach is on the opposite side and the intestine 

 below behind the foot. If this is not really a species, its internal ar- 

 rangement differs most curiously from the type form. 



Family XVIII. Brachionidse. 



42. Brachionus eakeki, Ehreuberg. 

 Specimens with the broad-based lateral spines drawn by Gosse, and 

 with the occipital spines comparatively small, are of common occurrence. 

 Others differ greatly from this type, the lateral spines being thin from 

 their base and curved outwards, and the central occipital spines almost 

 as long as the lateral ones, the intermediate pair being very distinct and 

 far from obliterate. 



43. Brachionus urceolaris, Ebrenberg. 

 Fairly common. 



44. Brachionos militaris. 

 Many sjiecimens seen.

The foot of this species is of extraordinary length. In a specimen 

 measured after death the lorica was xiro" and the foot JL" and it was 

 wrinkled. In living specimens the foot is often extended so as to be 

 three times as long as the lorica. In shape it resembles B. urceolaris 

 from which it differs in some minor particulars. The occipital spines are 

 somewhat moi'e deeply cut, the pectoral edge rises considerably and has 4 

 undulations the two middle ones of which are slightly notched. Viewed 

 dorsally the edge of the lorica appears round, and the spines bounding 

 the orifice of the foot cannot be seen excejjt through the shell ; a ventral 

 view shows that these spines are placed farther forward than the dorsal 

 extremity of the lorica, and a side view shows that the dorsal edo-e of 

 the lorica projects so that the shell from this edge to the spines is a 

 curve inwards. The dorsal view of the foot-orifice, i. e., of the spines and 

 the space between them, is peculiar, the inner surface of the spines being 

 rounded and the edge between their bases having an outward curve.
