SPONGES 
HABITS OF LIMY SPONGES. 
Limy Sponges are usually found in abundance in our New England Wat- 
eis in the shade of docks, bridges, and wharf piers and on sea weeds, but al- 
most always out of the direct rays of the sun. | 
COLOR OF LIMY SPONGES. 
All of the Limy Sponges which I have seen were either white or pale yel- 
lowish, and this absence of color would appear to result from their habit of 
living out of the sunlight. They always occur in moderately shallow water. 
GEOGRAPHICAL RANGE OF LIMY SPONGES 
It is highly probable that Limy Sponges have about the same range as 
Salt Water Silicious Sponges, throughout the temperate, tropical and sub- 
tropical seas, but donot extend as far north nor south. 
SPONGES WITHOUT FIBER OR SPICULES. 
Sponges which fall under this head are peculiar, inasmuch as they have 
neither fiber nor spicules. The substance of the sponge appears to be made 
up wholly of sarcode through which penetrates the water system. See Fig. 41, 
A, where I give a greatly enlarged section of one of these sponges, showing 
the water system. B shows the surface of the sponge which appears granular. 
Both cuts are magnified about fifty diameters.
