88 EXPERIMENT STATION RECORD. 



paratively little economic importance, it deserves attention from an economic 

 standpoint largely because some scientists insist on identifying it witli the 

 highly important .17. miilticcps. A complete synonymy of the species is included. 



Historical sketches and the synonymy of 3 additional species of the genus 

 Multiceps are given, namely, M. lemuris, described from the liver and thorax 

 of Lemur maco; M. polytuherculosMS, described from the leg of the jerboa 

 {Dipus sagiita) ; and M. spalacis, described from Spalax capensis. Cysticercus 

 botryoides, described from the back muscles of a rabbit and Acephalocystis ovis 

 tragelaphi, from Ovis tragelaphus are retained under the original names as 

 species inquierenda. 



Two new species of Aprocta, A. Railliet and A. Henry {Bui. Soc. Path. 

 Exot., 3 (1910), A'o. 3, pp. 152-155). — Two species belonging to the nematode 

 genus Aprocta, one taken from the preorbital sinuses of a bustard (Otis tarda) 

 from Abyssinia, the other from the suborbital sinuses of a hooded crow ( Corvus 

 cornix), are here described as new to science. 



Some remarks of the genus Leucocytozoon, C. M. Wenyon (Parasitology, 

 3 (1910). No. 1, pp. 63-72). — In reviewing recent papers relating to parasites of 

 leucocytes, the author calls attention to the fact that as a generic term Leu- 

 cocytozoon must be restricted to the bird parasites, the leucocytic parasite of 

 mammals being excluded. "As the complete life cycle of the heraogragarines has 

 been followed in only one instance, there are insufficient data for splitting up 

 the group, so that it is at present safer to include in the group Hemogregarina 

 the hemogragarines of the cold-blooded animals and the very similar parasites 

 of the red blood corpuscles and leucocytes of mammals. If it be found that the 

 life-history of the leucocytic parasites of mammals differs markedly from that 

 of the type species of hemogregarine (H. minima) then the name Hepatozoou 

 of Miller will have priority." 



A bibliography of the literature referred to is appended. 



The leucocytozoa, a rejoinder to C. M. Wenyon, Annie Porter (Parasi- 

 tology. 3 (1910), No. 2, pp. 239-2U).—Au answer to the above. 



A Leucocytozoon of a turtle dove (Turtur humilis) and of a teal duck 

 (Querquedula crecca) from Tonkin, C. Mathis and M. Leger (Conipt. Rend. 

 Soc. Biol. [Paris], 68 (1910), No. 3, pp. 118-120).— In 4 of 9 turtle doves exam- 

 ined a Leucocytozoon was found to which has been given the name L. marchouxi. 

 This parasite could not bo found in any of six T. rupicola nor in 176 domestic 

 pigeons that were examined. 



Three of 8 teal ducks were found parasitized by a new species which has been 

 named L. simondi. 



RURAL ECONOMICS. 



[Eeport on small holdings and allotments, 1909], E. J. Cheney and M. T. 

 Baines (Bd. Agr. and Fisheries [London], Rpt. Land Div. 1909, pts. 1, pp. 108, 

 maps 2; 2, pp. 109-288; abs. in Jour. Bd. Agr. [Loiidon], 17 (1910), No. f,, 

 pp. 302-30ft). — This is a report of the small holdings commissioners under the 

 small holdings and allotments acts for the year 1909. Part 1 deals with small 

 holdings, and part 2 with allotments and miscellaneous land acts in Great 

 Britain. 



" Considerable progress has been made during the past year in satisfying 

 the demand for small holdings, and the position on December 31 last was that 

 60,889 acres had been actually acquired or agreed to be acquired for small 

 holdings by county councils in England and Wales, of which 34,234 acres had 

 been purchased for £1,107.215, and 26,6.55 acres leased for rents amounting to 

 £33,611. Of this land vacant po.ssessiou had been obtained of 38,126 acres, and 

 36,845 acres had been actually let to 2,793 individual small holders, and 28 acres
