Haddon — A New Species of Kakampa. 397 



Dimensions. — Length about 20 mm. ; diameter about 4*5 mm. 

 Habitat. — In sand, at Malabide, county Dublin, at low water. 



This is the first recorded example of this genus in Ireland ; it 

 was found on the shore at Malahide at low water by my friend 

 and former pupil. Miss A. Shannon, on September 13, 1883. 



Like the other species of the genus, this form usually lies 

 buried in the sand ; when free, it often adheres by its posterior 

 extremity, standing upright in the water, or it may lie prostrate, 

 adhering by some of the small wart-like suckers of its physa. 



I give myself the pleasure of naming this species after my 

 learned and laborious friend, Dr. A. Andres, Professor of Zoology 

 at Milan, to whom all zoologists are indebted for his most admir- 

 able Monograph on the Actiniae. 



The type specimen is deposited in the Natural History Museum, 

 Science and Art Department, Dublin. 



Two species of Halcampa have been previously recorded as 

 British, viz. H. chrysantheUum (Peach), and H. microps (Grosse) ; 

 the former from Cornwall, and the latter from South Devon. 

 The name of the first species stands ; but, as Andres has shown 

 in his Monograph of the Actinise,^ IT. microps, possessing as it 

 does sixteen tentacles, is undoubtedly an Edwardsia, and therefore 

 does not concern us at present. 



Analysis of the British Species of Halcampa. 



Tentacles with six white half-rings. Disc bluish in centre, 

 brown towards periphery, with pale inter-radial lines, which are 

 trifid towards the base of the tentacles. — JI. chrysantheUum
