num. He had in his possessiou a Tick, distended with blood, half 

 an inch in length, which came from Camp Sheridan, Nebraska, 

 agreeing in all respects with those from Beach Haven. 



Amblyovima differs from Ixodes in the possession of eyes, and he 

 was by no means satisfied that the Beach Haven Ticks possess such 

 organs, unless they form the prominent posterior angles of the head. 

 The Ticks have been supposed to feed on vegetable matter until 

 they reach maturity. As the mouth organs of the larva do not 

 differ from those of the adult, he thought this doubtful. 



In the American Entomologist, 1870, p. 160, vSeed-Ticks found 

 under the bark of apple trees are stated to be the young of one of 

 our most common Wood-Ticks, Ixodes unipiindata, but he thought 

 this has not been positively determined to be the case. 



He had been repeatedly told of a minute tick, commonly called 

 the Seed-Tick, not uncommon in our vicinity, which attacks man 

 and buries itself beneath the skin. He had suspected it to be the 

 young of Ixodes, but had no opportunity of determining the question. 



Note. — The following day, September 24, the young Ticks ap- 

 peared generally less active, and many were motionless and seemed 

 dead. Thirty active ones were placed on the inside of his fore-arm, 

 and there remained for ten minutes, but as they wandered about 

 aimlessly and with no apparent disposition to attach themselves, they 

 were removed. 



Though the young Ticks had not fed, they actually seem to have 

 grown, for at the present time they generally measure 0.725 mm. in 

 length by 0.45 mm. in breadth. 



The adult male and female appear about the same size, for the two 

 range from i-8th to 3-i6ths of an inch in length. One of those dis- 

 tended with blood measured 9-i6ths of an inch long by 6-i6ths in 

 breadth, and similar specimens after having laid their eggs had 

 shrunken to 7-i6ths by 5-i6ths. 



Finally the.same day the Ticks were placed in alcohol for preserva- 

 tion.

Parasites of Mola rotunda.— Vxoi. Leidy stated that one day during 

 his stay at Beach Haven, N. J., while men of the life-saving station 

 were directly off shore watching the bathers in case of accident, a 

 Sun fish, Mola rotunda, approached the boat, apparently, as they 

 supposed, sleeping. The fish, weighing nearlj^ two hundred pounds, 

 was readily taken without resistance. It proved to be of additional 

 interest from the great number and variety of parasites with which
