Studies on the Musculatory System and Mouth Parts of Laelaps Echidninus Berl.*

Abstract

Some time ago, while working with rats containing the rat trypanosome, T. lewisi, the writer became interested in the small ectoparasitic mite Laelaps echidninus Berl. which is commonly associated with them. Since the literature on the internal anatomy of Gamasids is not voluminous, and is in general somewhat vague as to exact details, a careful study of mouth-parts and the musculatory system seemed desirable and yielded results which it seems desirable to place on record as a starting point for future work.
