MONTEIRO, J. C.  and  COELHO, A. C. S.. Comparative morphology of Astraea latispina (Philippi, 1844) and Astraea olfersii (Philippi, 1846) (Mollusca, Gastropoda, Turbinidae). Braz. J. Biol. [online]. 2002, vol.62, n.1, pp. 135-150. ISSN 1519-6984.  http://dx.doi.org/10.1590/S1519-69842002000100016.

The present study examines comparatively the soft parts of turbinids Astraea latispina and Astraea olfersii. The characters of soft parts of these species, in agreement with Trochoidea organization, allow a differencial diagnosis on the cefalic lappets, appendix of eye-stalk, hypobranchial glands, jaws, radulae, and stomach spiral caecum, which information will be helpful in taxonomic studies.
