136 A— d) average 0.96— 0.97 mm In diameter, are spherical, transparent, and of a 

 reddish or reddish yellow hue, and have a moderately broad perivitelline space. They 

 have no oil globule, though the yolk contains many minute globules that tend to unite 

 as development proceeds. The eggs sink and are so sticky that they cling to each other 

 or to anything on which they chance to come to rest. 



Jeffers has observed that incubation occupies c^^ days at a temperature of o°C, 30 

 days at 5° C, and 1 5 days at 10° C, with about 1 2° the upper maximum, though the eggs 

 may hatch in water as warm as 15° and in salinity as low as 7 "/oo {46 [1931]: 17, 18).
