A Guide to the Birds of the West Indies
This book presents a meta-anatomy of the Bird Family and Regional Identification Guides and discusses its use as a guide to species coverage and taxonomy.

- 1 March 1985
Although Cuba has strict hunting regulations and protective laws, as well as an excellent system of preserves, some species and races of Cuban birds are endangered. Here, I discuss the current status…
Nutritive Egg Formation in the Marine Snails Crepidula dilatata and Nucella crassilabrum
These findings suggest that, at least in C. dilatata, the mechanisms of nutritive egg formation reside in properties of the oocyte, and that this snail's dimorphic eggs are not correlated with the fate of these cells.
Ultrastructure of sperms in bivalve molluscs of the Mytilidae family
The sperm structure of five external fertilizing bivalve molluscs pertaining to the Mytilidae family is compared to see if such gamete structure conforms to the primitive sperm form of the type I predicted by Franen.
A New Species of Tropidophis from Cuba (Serpentes: Tropidophiidae)
Tropidophisfuscus is described from native pine forests of eastern Cuba and in some aspects of scalation and coloration, it resembles species in the maculatus group, whereas in habitus it resembles members of the semicinctus group.
A New Snake of the Genus Tropidophis (Tropidophiidae) from Eastern Cuba
A small, spotted species previously confused with Tropidophis haetianus of Hispaniola is described from the northern coast of eastern Cuba, and is tentatively placed in the maculatus species group.
Ultrastructural analysis of spermiogenesis and sperm morphology in Chorus giganteus (Lesson, 1829) (Prosobranchia: Muricidae)
Spermiogenesis and sperm morphology in the marine gastropod Nucella crassilabrum with an account of morphometric patterns of spermatozoa variation in the family Muricidae
Spermatid differentiation and the morphology of mature spermatozoa in Nucella crassilabrum, a muricid snail, was investigated and two morphometric patterns of sperm structure are distinguished and their functional significance discussed.
