“…When comparisons are carefully made of the blood of Linnt/ns which have been equilibrated with normal Woods Hole sea water, 31-32/^c, the serum has been found to be isosmotic within \% (freezing-point data of Carrey, 1905 andof Dailey, Fremont-Smith andCarroll, 1931, also the present data using a thermoelectric vapor pressure method). Cole (1940) states that 6 pooled samples of Linnilus blood collected over 3 summers were "consistently hypertonic" and thinks that this is the normal condition.…”

“…In normal sea water there is dispute about whether the animal is isosmotic (Garrey, 1905;Dailey, Fremont-Smith and Carroll, 1931) or hyperosmotic (Cole, 1940;and Homer W. Smith, in Cole, 1940). McManus (1969) states that Limnlns is approximately isosmotic in water of about 25 f / (C salinity, and finds that large specimens (prosomal width 15 cm or more) in water of about 7%o were slightly hyperosmotic after 24 hours.…”

Limit! us polyphemus is one of the four living species of horseshoe crabs, a group with a geological history which can he traced back to the Silurian (Neolimulus] and even to the Cambrian (Stp'rmer, 1952). The Mesozoic species originally referred to the genus Limn Ins are closely related and similar to present-day forms and Mesolimulus wale hi of the Jurassic Solnhofen lagoons co-existed with a fauna which included jelly-fishes, swimming crinoids and ammonites (Abel, 1927). During the intervening 135 million years (Howarth, 1964) the xiphosurans of the lagoons and seas covering parts of Germany, France, England, Sweden and N. Africa have disappeared leaving three living genera, one on the east coast of North America (Limit/us), and the other two on the south-east and east coasts of Asia (Tachyplcns and Carcinoscorpins) (Stunner, 1952).
