I would appreciate if you could add this message in a future issue. Thank you very much Subject: Request for Lagenorhynchus cruciger information – working paper. My name is María Constanza Marchesi, I am an undergraduate biology student from Argentina. Right now I am working on my thesis work on the biomechanical properties of the vertebral column of two dolphin species belonging to the genus *Lagenorhynchus. *I am also working with Dr. RNP Goodall on a new paper about the osteology of the hourglass dolphin *Lagenorhynchus cruciger.* This is a circumpolar species and there is not much information available so we are looking for any information about this species for the period 1997 - 2011: sightings, specimens found (collected or not collected) but specially information regarding the osteology of this species (cranial measurements based on Perrin 1987 when possible but especially vertebral counts and post cranial measurements and meristics based on Perrin 1987) We are also asking for a particular publication: Miyazaki N; Shikano C (1997) Preliminary study on comparative skull morphology and vertebral formula among the six species of the genus Lagenorhynchus (Cetacea : Delphinidae). Mammalia, vol. 61, no4, pp. 573-587. We have written to the first author but apparently there is a failure with the email address. Any help would be a huge help!
