Thirteen essentially (holo)pelagic species of Mysidacea (Lophogastrida and Mysida), plus ve benthopelagic species were taken with vertical plankton hauls (mostly 1000-0 m depth) and by examining the stomach contents of benthopelagic sh (from 550-700 m) in restricted areas of the NE Atlantic Ocean. The families Gnathophausiidae, Lophogastridae, and Eucopiidae are each represented by two species, the Mysidae by 12 species. A rst description of the previously unknown male and a supplementary description of the female are given for Longithorax alicei, so far known only from the Canary archipelago. First records for the northern hemisphere are given for two South Atlantic species, Boreomysis bispinosa from the Cape Verde archipelago and Katerythrops resimora from the Canary Islands. Additional new records for the Canary Islands are Gnathophausia zoea, Lophogaster spinosus, and Longithorax nouveli. Among the 12 species of Mysidae examined, ten showed statoliths mineralized with uorite (CaF), while two Boreomysis species showed comparatively soft, non-mineralized statoliths. Most of the 29 pelagic species so far known from the Selvagens, the Canary, and the Cape Verde Islands belong to the circumtropical deep-water fauna. The local pelagic fauna shows no particular correspondence with that in the Mediterranean, because the two areas have almost nothing but ubiquitous species in common. By contrast, ten benthopelagic species so far recorded from pelagic (plankton) samples off the Canary Islands are endemic in the eastern Atlantic, in most cases including the Mediterranean. 5 /

Results on the zooplankton (Chaetognatha and Mollusca) collected during the Vulcano project (cruise Vulcano 0313, Vulcano 1013) after the eruption in El Hierro Island (Canary Islands) are presented. These results are compared with preceding information from TFMCBM/1991 and TFMCBM/2009 cruises supported by the Natural History Museum of Tenerife island, previous to the eruptive process wich affected this area.

En el presente trabajo se relacionan los especímenes tipos depositados, hasta el momento, en las colecciones de Biología Marina del Museo de Ciencias Naturales de Tenerife (islas Canarias), que incluyen registros (75 holotipos, 129 paratipos y 4 neotipos), relativos a cnidarios, moluscos (en parte), peces, anélidos (poliquetos) y quetognatos. Se especifica el número de catálogo y el status del tipo, al igual que las referencias bibliográficas que contienen la descripción original del animal y otras relacionadas con modificaciones taxonómicas del especimen tipo.

“…sí, sí, sería muy ventajoso para las ciencias, y principalmente para la geografía y la navegación, enviar a las islas Canarias a una persona acostumbrada a viajes marítimos y ejercitada en observaciones…”
