II and III deal with animal parasites, Part IV with vegetable parasites, 

 Part V with technique; the arrangement of Parts II-IV is by taxonomic 

 groups. Dr. Underbill divides his subject matter into Part I, The 

 External Parasites (pp. 1-154, including two general chapters) ; Part II. 

 The Internal Parasites (pp. 155-310), and Part III, The Pathogenic 

 Protozoa (pp. 311-352) ; within each part the sequence of topics is that 

 of the systematist. To each of his chapters Dr. Rivas has added a list 

 of selected references to the appropriate literature. Each teacher of 

 parasitology has his own preferences as to the method of treatment 

 of the subject and no doubt these two additions to the growing list of 

 books on medical and veterinary entomology will prove to be desirable 

 to many who are not altogether satisfied with previous texts. P. P.
