Twenty-four New Species of Botifera. By P. H. Gosse. 5 



somewhat deeper in hue ; while in one was an immense egg, of a coffee- 

 brown, almost opaque, whose appearance suggested the probability that 

 the species is strictly oviparous. The acute hooked proboscis is very 

 conspicuous. The corona, scarcely divided, is not wider than the neck at 

 the antenna, and this neck is not swollen into a collar. The penultimate 

 spurs are very minute cones, whose bases are not separated by an 

 interspace (fig. 14, ^). The whole central body is indented with 

 longitudinal furrows. The mallei are destitute of visible teeth. (Fig. 14.) 

 The animal is remarkably sluggish, rarely swimming, but turning its 

 head slowly and aimlessly from side to side. It has occurred in 

 Woolston Pond. 



15. Synch^ta longipes. In front much like S. pectinata, but with 

 the foot distinct, separated, long, furnished with two small toes. 

 Length 1/173 in. Lacustrine. 



The well-marked foot, having a rhomboid outline, common to all 

 the eight or ten specimens that I examined, appeared to me sufficient, 

 when combined with its small dimensions, to distinguish this species 

 from S. peotinata, with which else it has much in common. The broad 

 head bears four frontal warts and two setae. It has occurred in some 

 profusion in fresh water near Dundee. (Fig. 15.) 



16. Euchlanis oroplia. Lorica roof-shaped with sloping sides, but 

 not rising to a ridge, yet cleft for a short distance behind, between 

 two descending extremities. Ventral plate flat, thin, much smaller in its 

 whole outline than the carapace : foot with a single seta or none ; toes 

 thin, blade- shaped. Length, total, 1/75 in. Lacustrine. 



This is a noble species, and not uncommon. The posterior fourth 

 of the ovate lorica seems as if pinched-in, and the dorsal edge of this 

 portion becomes a low double carina. In fig. 16, h, the inner outline 

 is that of this portion (posterior to \ in the upper figure), the outer 

 outhne represents a transverse section at * in the upper figure. (Fig. 16.) 



17. Disiyla striata. Lorica as in D. Gissensis, but covered with 

 longitudinal sulci; the front margin projecting in two lateral points 

 (which, however, are lost in the protrusion of the head, by the evolution 

 of flexible membrane) : toes slender, straight, more than half as long as 

 lorica, pointed, not shouldered. Length 1/130 in. Lacustrine. 



The lateral infold is narrow and nearly closed. The dorsal sulci 

 are about eight in number, slender and superficial : foot a long large 

 bulb, not divisible into joints ; toes long, nearly straight, rods. The 

 dorsal surface is corrugated, besides the sulci ; there is a minute eye, 

 difficult of detection. Two examples occurred in water sent me by 

 Dr. F. Collins from the pool at Sandhurst Military College. (Fig. 17.) 



18. Asplanchna eupoda. Body globose, with a stout foot, retractile 

 at will : rami of incus long, each armed on its inner edge with four 

 widely-severed teeth. Length, moderately extended, 1/52 in., width 

 1/118 in. Lacustrine. 



The most remarkable feature is the foot, which is, proportionally, 

 much larger than in A. myrmeleo. The pincer-like rami are those of a 

 normal Asplanchna, having a close resemblance to those of A. priodonta, 

 save that their inner edges are not cut into saw-teeth, but beset with 

 three distant spinous teeth, while each curved point is double. I have
