Spermathecae 1+2, globular, vesiculate or subspherical, without acute projections.

Subsequently, a small volume of andesitic magma, probably generated at a deeper crustal level (lower crust (?): 25-45 km; Ortega-Gutierrez et al., 2008), intruded in the shallow magma chamber, losing heat to the surroundings and starting to vesiculate. Eichelberger et al.

In contrast to GAs isolated from squid, which vesiculate but do not form a seal 1-2 h after severance (7), transected crayfish medial GAs vesiculate and do seal within I h after severance (2-4).

The predominant population of neoplastic cells were polygonal with distinct cell borders, a moderate amount of eosinophilic to amphophilic lacy cytoplasm, and an irregularly round to oval nucleus possessing vesiculate chromatin and 1-2 prominent nucleoli.
