Fig. 373. blr, blood lacunre; ea. Concerning the internal organs-but few general remarks can be made. Salivary glands are wdiolly absent; on the other hand, the stomodeum is usually widened into a strong chewing 'stomach,' and behind this empty the ducts of the so-called liver. Tliis varies lietween the two simple blind sacs of the Daphnidte (fig. 383) and the enormous livers of the Decapoda (fig. 400, -4). It is not exclusively glandular (hepato-pancreas), but is an expansion of the digestive tract, and- like it partakes in the resorption of nourishment. Excretory organs are represented by so-called green glands.
