220 Dr. W. C. Mcintosh on the Zoophytes of St. Andrews. 



Fam. 6. Hyauthidae. 



Genus 2. Peachia, Gosse. 



Peachia hastata^ Gosse, Brit. Anem. p. 235, pi. 8. fig. 3. 



Thrown ashore on the West Sands after storms in great 

 numbers, and was thus first found in Britain bj Dr. John 

 Reid, of St. Andrews, who published a description of his 

 single example in 1848 (Physiological, Anat., and Pathol. 

 Observations, p. QbQ^ jdI. 5. f. 21 & 22) : his title {A. cylin- 

 drica) has therefore a prior claim to that of Mr. Gosse. It 

 occurs also in the stomach of the cod. 



Genus 4. Edwaedsia, De Quatrefages. 



Edwardsia callimorpha^ Gosse, Brit. Anem. p. 255, 

 pi. 7. fig. 7. 



A variety was found on the West Sands after a storm in 

 March, with brown instead of the usual whitish specks. It is 

 an elongated form inhabiting sand. 



Edwardsia AUmanm, ]V(^'I., Proc. Roy. Soc. Ed. 1864-5. 



From a shallow pool on the West Sands after a storm in 

 October. It inhabits a distinct case, and can retract its ten- 

 tacles and cover them by the external border of the disk. The 

 latter is marked by eight alcyonarian divisions or radii, and 

 has always a ragged border of the investing sheath. The 

 disk has a pale brownish colour. 



The tentacles are simple, rather blunt, pale and translucent, 

 with a white streak in the centre ; the rim of the mouth is 

 occasionally protruded as a conical process. 



This form exhibited none of the " remarkably vigorous and 

 spasmodic contractility " ascribed by Mr. Gosse to the family ; 

 for it was comparatively inert. 



Edwardsia Goodsiri^ M'l., Proc. Roy. Soc. Ed. 1864-5. 



Found at the same time and place with the former. Ten- 

 tacles 15, translucent, longer than the diameter of the oral 

 disk, and not much tapered. A whitish ring occui'S at the 

 tip of each, and from the base a white spear-head with a 

 transparent centre reaches more than halfway up. Oral disk 

 streaked with white and brown. It is somewhat allied to E. 

 Beautempsii, DeQuatref.*, but is distinguished by the marks 

 on the tentacles, which in the latter only have the tip 

 " d'un beau jaune rougeStre." The posterior end of the ex-
