Gordiodrilus is the name of a new genus of Oligochzta provision- 
ally placed in the family of Ocnerodrilide by its describer, F. E. 
Beddard (Ann. and Mag. Nat. Hist., ser. 6, Vol. x, No. 55). The 
genus comes near the American genus Ocnerodrilus, which later 
reaches its greatest development, as far as is known, on the Pacific 
Coast. Gordiodrilus differs from Ocnerodrilus in having only one 
cesophageal diverticulum in somite ix, Ocnerodrilus having this organ 
paired. The male or spermduct,which in Ocnerodrilus opens in so- 
mite xvii, always in the same pore asa prostate, opens in Gordiodrilus 
in somite xviii, always in a different pore from the prostate, but in the 
same somite as that organ. Beddard describes five species of Gordi- 
odrilus from Africa and the West Indies. The memoir is very in- 
teresting to’ Pacific Coast investigators, as the new genus forms a 
connecting link between Ocnerodrilus and the higher terrestrial 
Oligochzta. Here may be incidentally mentioned that a new 
genus not yet described, recently found in Baja California, is in 
many respects intermediate between Ocnerodrilus and Gordio- 
drilus, having one pair of diverticula in somite ix, originating in the 
anterior part of the somite. The spermduct opens in somites xviii 
and xvii, the posterior one independently of the prostates, one pair of 
which open in somite xvii and one in xix. G. E. 
‘‘Expedition a la gruta de Cacahuamilpa.’’ Under this heading 
we find a memoir of twenty pages, describing the results of a col- 
lecting expedition to a cave called ‘‘Cacahuamilpa,’’ somewhere in 
Mexico; the exact locality is not given (‘‘ E] Estudio,’’ Tom IV, No. 
8, Mexico, Sept., 1892). 
The memoir is accompanied by two plates containing forty-five 
drawings of animals, described as new in a most singular manner. 
There are eleven species pretended to be new, ranging in almost as 
- many different families, from Coleoptera to mollusks and mammals, 
and all are given as specific name ‘‘cacahuamilpensis.’’ Many 
species are given a new name, probably in order that all may be 
uniformly ‘‘cacahuamilpensis,’”’ though the old and first name 1s 
sometimes kindly appended. The descriptions are such that not a 
single species can be identified, not even as to genus, and the figures 
are in the style of those seen in our daily newspapers. 
It would have been much better to distribute the collections 
to specialists than to disgrace the zodlogical literature in this way.
