female katipo in an empty, clear glass bottle; she at once began to make a 
fine irregular web, and, on the morning of the 8th, I found that during the 
night she had constructed and suspended near the neck of the bottle, a 
spherical cocoon, composed of a pale yellow silky web, through which one 
could see the purplish eggs; for the next two months the spider remained 
on or close to the cocoon ; I put several flies and other insects into the 
bottle, all of which she at once killed and threw down to the bottom without 
eating. Early in January she shifted the cocoon close to one side of the 
bottle at the shoulder, and took up a position for herself three-quarters of 
the distance from it to the bottom of the bottle. By this time she was 
reduced to half the original size and was very inert, and, on the 7th 
February, 1878, sixty young katipos issued from the cocoon. Next morning 
the mother lay dead at the bottom of the bottle; it must not be supposed 
that the old spider always dies in this way, for I had one which ate the 
greater part of her family before doing so. The young ones are of a semi- 
transparent white, with two lines of black dots on the abdomen, and black 
joints to the legs, the underside of the abdomen being brown, with an 
irregular whitish centre.

Tur publication of a * Catalogue of New Zealand Crustacea’ by the Geolo- 
gical Survey and Colonial Museum Department, has proved a great boon to 
students and collectors in the colony, by bringing together, in a convenient 
form, descriptions of all the species known to inhabit these shores, thus 
enabling them to pronounce, with some degree of certainty, upon any speci- 
men which may be under discussion. 
The remarkable resemblance which our fauna bears to that of England 
and California has been pointed out by many authors. I have now to 
record the occurrence here of at least two additional European and tho 
same number of Californian species. 
Three of the species mentioned in this paper, viz., Caprella lobata, C. 
nova-zealandiz, and Ebalia tumefacta, were obtained in Cook Strait, in 
January, 1876, whilst dredging for the telegraphic cable.

The coxæ of the pereiopoda are not squamiformly developed, some or 
all being fused to their respective segments. The pleon has one or more of 
the segments absent,
