annelids in many ways, but its segmentation is much more pronounced. 
The gonads are also remarkable ; thus, the female shows hints of her- 
maphroditism in the possession of rudimentary seminal vesicles; and 
there are vaguer hints in the male, where spermatozoa arise from two 
different tissues, endodermic and mesodermic, at once. The author 
concludes her account of this highly interesting form with a comparison 
between it and Peripatus. 
Notes on Qligochsetes.* — Mr. E. S. Goodrich has an account of a 
new species of earthworm which he calls Enchytrseus hortensis. As he 
has found it near Oxford, London, and Weymouth, it is probably distri- 
buted all over England. When full-grown, it is about 15 mm. in 
length, and milky white in colour. He enters with some detail into an 
account of the structure of the nephridium, and, as he was able to 
observe it in the living animal, he is able to correct some errors into 
which he thinks Bolsius fell from employing the method of sections 
alone. 
The coelomic corpuscles of this worm are most characteristic, and 
are of three kinds. One variety is very characteristic of the Enchy- 
traeidae in general, and has been described by almost every writer on 
this group of the Oligochaeta. A variety of these contains a refringent 
body which is found on examination to be formed of a long thread of 
transparent homogeneous substance, closely coiled like a rope. On the 
function of these threads the author is unable to throw any light. As 
in some other forms, the spermatheca of this new worm fuses with, and 
opens into the oesophagus. 
The author has made a study of the action of chemical reagents on 
the coelomic corpuscles of this worm, and of the Vermiculus pilosus which 
he described some time since. He finds in them at least four distinct 
endoplastic products, aud perhaps three distinct chemical substances, 
which are probably of an albuminoid nature. None are mucin or chitin, 
nor are they of a fatty or a starchy nature. Mr. Goodrich finds in the 
cuticle and setae of the common earthworm three albuminoid substances 
distinct from each other, and from those found in the coelomic corpuscles. 
In the common earthworm, though not in the two other genera just 
mentioned, the setae appear to be chiefly composed of chitin, or of some 
substance closely allied to it. 
Gigantic Earthworm from the Pyrenees.! — MM. J. de Guerne and 
R. Horst give an account of a large earthworm taken near d’Ahusquy. 
This station is 920 metres high, and the winters there are both long 
and severe. When extended these worms cannot be less than 40 cm., 
and there is little doubt that the species is Allolobopliora gigas , which 
was discovered byDuges near Montpellier. The zoologists of that place 
should rediscover the worm for themselves, and give us a detailed account 
of it. 
Supra-CEsophageal Gland of Haementaria officinalis.^ — Herr H. 
Bolsius finds in this leech a tubular organ which he has not observed 
in any of its allies. This tube lies above and along the proboscis, and
