We carried out a definition of the species group to which Conus praecellens A. Adams 1854 belongs using a combination of comparative morphological data, molecular phylogeny based on standard genetic markers and toxinological markers. Prior to this work, Conus praecellens was generally postulated to belong to a clade of similarly high-spired, smaller Conusspecies such as Conus pagodus Kiener, 1845, Conus memiae (Habe & Kosuge, 1970) and Conus arcuatus Broderip & Sowerby, 1829. The molecular phylogeny and toxinological data demonstrate that these prior hypotheses are incorrect, and that instead, Conus praecellens is in a branch of Conus that includes Conus stupa (Kuroda, 1956), Conus stupella (Kuroda, 1956), Conus acutangulus Lamark, 1810 and surprisingly, some species that are morphologically strikingly different, Conus mitratus Sowerby, 1870 and Conus cylindraceus Broderip & Sowerby, 1830. A more careful analysis of the morphologically diverse forms assigned to Conus praecellens suggests that from the Philippine material alone, there are at least three additional undescribed species, Conus andremenezi, Conus miniexcelsus and Conus rizali. A reevaluation of protoconch/early teleoconch morphology also strongly suggests that Conus excelsus Sowerby III, 1908 is related to these species. Together, the different data suggest a clade including the 10 species above that we designate, the Turriconus (Shikama and Habe, 1968) (clade; there are additional distinctive forms within the clade that may be separable at the species level. The phylogenetic definition using the multidisciplinary approach described herein provides a framework for comprehensively investigating biodiverse lineages of animals, such as the cone snails.

FORTY New England greenkeepers battled through the championship tournament which was held at the Brae Burn Country club, Newton, Mass., on October 8. Handicap medal play with four prizes and with the two best medal players competing for the title at match play was the order of the day. Ted Swanson of Bear Hill tallied an 84 in the morning round to an 87 for R. Wallace Peckham of Sachuset, but the latter was on his game in the afternoon, winning 6 and 4. Alex Ohlson of the Lexington Golf club, winner last year, did not compete. The four net winners were E. D. Pierce, Kittansett; Bill Lindsay, Manchester, N. H.; J. C. Adams, Pinewood; and Joe Oldfield, Brae Burn. The guest's prize went to P. W. Chase, and Jim Sullivan of Waltham, captured the prize for men over 50 years of age. ::..
