ZOOLOGY. 
Tue Jigcer FLEA. — The jigger or chigoe, a species of flea (Pulex 
penetrans) which burrows in the feet of men in tropical America, has 
within late years been studied by Karsten, Guyon, and Bonnet. Our 
figures have been taken from these works, and were originally used to 
illustrate the Danish Journal for the Popular Diffusion of Natural Science. 
The eggs (Plate III., Figures 1, 2) are either dropped upon the ground, 
or remain within the sacs of the gravid female. The larve (Figure 3) 
transform in a cocoon (Figure 4) into the pupa (Figure 5), as in the 
ordinary flea. Figure 6 represents the fecundated female; Figure 7 
the same at the third day from its entrance under the skin; Figure 8 
the same after several days’ residence in the skin of its host. Figure 9 
represents the fully grown female, seen in front and magnified only four 
times; Figure 10, the head of the same still more enlarged. Figure 11 
represents the female before it has entered the skin of its host, and Fig- 
ure 12 the mouth parts, much enlarged (w, mandibles; d, maxillary 
palpi; u, under lip or labium). 
ANTHROPOLOGY. 
ANTHROPOLOGICAL News. — Some account was given in our last 
number of anthropological papers read at the American and at the 
British Association. The following are some of those communicated to 
the French Association: Déformations craniennes occasionnées par la

ment of the Plans for the Anthropological Exhibition at Paris in La

GEOLOGY AND PALHONTOLOGY. 
Recent PALÆONTOLOGICAL Discoveries. — Professor Cope re- 
cently announced the discovery by Mr. C. M. Wheatley, in the trias of 
Pennsylvania, of a large saurian, which he named Paleoctonus Appala- 
chianus. Since that time Mr. eatley has obtained material which 
demonstrates that the reptilian life of that period in the East was rich 
in types. This includes teeth of two other individuals of the sauriaD a ; 
named, and teeth of six other species. Two of these, the Belodon 
priscus and B. Carolinensis, had been previously known, while three 
others of larger proportions are new to science. They have been named
