This now is the second compendium of articles dealing with the fossil otoliths that were collected from Central America during several decades. Following the initial study of the otoliths of the mesopelagic lantern fishes (Myctophidae) published as the first part of the ongoing investigations in Palaeo Ichthyologica volume 13 (SCHWARZHANS & AGUILERA, 2013) and a review of the otoliths of the marine catfish family Ariidae (AGUILERA, MORAES-SANTOS, COSTA, OHE, JARAMILLO & NOGUIERA, 2013), we are now covering the drum fishes (Sciaenidae) and cusk eels (Ophidiiformes).

Most of the otoliths studied for this compendium were obtained from young Neogene strata, chiefly of late Miocene (Tortonian) to middle Pleistocene (Calabrian) age. Clearly, one has to expect many Recent species to be retrieved from so young strata. Therefore, a good command of the otoliths of the relevant extant fishes of the region (and beyond) is a prerequisite for everybody attempting to identify such otolith assemblages. Consequently we have focused first on selected groups of fishes for which adequate knowledge of Recent otoliths is available or could be made available with reasonable efforts. Fortunately, they are also the most common and diverse groups of fishes and they represent the prime environments sampled, as is exemplified in the graph below.

We plan to continue with our task of describing the Neogene otoliths of tropical America in further studies. However, the knowledge base is often much less comprehensive of otoliths of extant species of those fish families still outstanding and therefore identifications at the species level may not always be possible in the extent desirable. It is our aim to try to accomplish an adequate data base of pertinent Recent species as good as possible in the course of our quest to extract the maximum possible information of this extraordinary collection.
