146 General Notes. [February, 



on each side of the cutting edge with about a dozen notched and 

 ciliated spines. Two or three short, stout and serrated spines at 

 the posterior angle. A number of stiff, slender hairs planted 

 among the spines. Dactylopodite scythe-shaped, bent rather ab- 

 ruptly near the base, then straight, and finally incurved near the 

 tip. Propodite of second foot more elongated than in the first 

 foot, and with a more oblique palmar surface ; armed with about 

 fourteen spines along each side of the cutting edge. The first, 

 second, and third abdominal segments have their postero-lateral 

 angles drawn backward into a decided tooth. 



Of the three pairs of caudal stylets, the first extends backward 

 beyond the second; the second beyond the third. The latter 

 consists of a stout peduncle and a single ramus, which is about 

 two-thirds as long as the peduncle and provided with a few slen- 

 der spines. There appears to be no inner ramus, but there is 

 to be seen on the inner side of the ramus present a process 

 of the peduncle that represents, perhaps, the inner ramus. 

 There is, however, no involution of the integument at the base of 

 this process. Telson elongated, twice as long as broad, the sides 

 nearly parallel. The posterior border is provided with a notch 

 that extends nearly three-fourths of the distance to the base. 

 Each prong is armed at the tip with from three to five spines. 



This species differs from C. gracilis more particularly in the 

 form of the telson, and in the length of the outer ramus of the 

 posterior stylets as compared with the peduncle. From C. anten- 

 natum Packard (American Naturalist, 1881, p. 880), it differs in 

 the form of the telson, and in the much greater size of the eyes. 

 Found by myself about 1st of April, 1880, in a rivulet flowing 

 down the limestone hills into the Noxubee river, at Macon, Miss.

The three species, C. gracilis, C. bifitrcus and C. Incifugus 

 present an interesting gradation in the forms of the posterior cau- 

 dal stylets. In the first-named the outer ramus is twice the 

 length of the peduncle, and the inner ramus is present, but rudi- 

 mentary. In C. bifitrcus the outer ramus is but two-thirds as long 

 as the peduncle, while it is doubtful whether there is anything 

 whatever to represent inner ramus. In C. lucifugus both the outer 

 and inner rami are absent, and the peduncle itself is much re- 

 duced. — (To be Continued). — 0. P. Hay, Irvington, hid. 



Revival of Tardigrades after Dessiccation. — The truth 

 of the occurrence of this phenomenon has been denied by various 

 observers, and the appearances explained by Ehrenberg as due to 

 the development of fresh specimens from eggs left by the animals, 

 which die in the process. Professor Yung, however, considers 

 that his observation of the process, in a single specimen of Mil- 

 nesium, proves the correctness of the old opinion. The specimen 

 was taken from a ditch, contained eighteen eggs, and manifested
