The immature stages of Ixodes tatei Arthur (Ixodidae)

The original description of Ixodes tatei was given by Arthur (1959) and based on three females taken from a rock partridge of unknown species and from a fox (Vulpes sp. ?) in Jarmo, Chemchemal Valley, Kirkuk (type locality) and the Zagros Mountains, Erbil, both in north-eastern Iraq. The material, on which the following account is based, consisted of two females, one gorged nymph, one slightly fed nymph and two fully gorged larvae. They were collected from the head of Alectoris graeca, which was shot about 20 km south of Jerusalem on 17 December 1966 and sent to me by Professor O. Theodor of the Hebrew University. One female, one nymph and one larva have been deposited in the Hebrew University, Hadassah Medical School, and one female, one nymph and one larva are retained in my collection. The holotype female is deposited in the Chicago Natural History Museum, Cat. no. 84472.

A UNIVAC Analysis of Sherd Frequencies from the Carter Ranch Pueblo, Eastern Arizona

Three factors contribute to differences between archaeological samples: sampling error and functional and temporal differences between the parent populations from which the samples are drawn. Many archaeologists have explained such differences as due only to temporal variations between the parent populations, thereby ignoring sampling error and relegating functional specificity to a minor role.A statistical analysis of potsherd frequencies in samples made by the Chicago Natural History Museum from an eastern Arizona pueblo, the Carter Ranch site, was undertaken using UNIVAC. By taking into account sampling error, differences between parent populations appeared that could most logically be attributed to functional differences. From the calculations, four possible functional constellations of pottery types were discovered, four types of rooms were isolated, a probable ceremonial complex of five pottery types was established, and differential areal disposal of sherds was found. It was impossible to demonstrate temporal differences between provenience units on the basis of sherd frequencies. Any such differences played a minor part in contributing to sample variation as compared to functional differences between provenience units.
