 and in their relaxed state, they resembled Muller's figure, but not 

 while vigorous." 



Virgularia diifers from Pennatula remarkably in this that no spi- 

 cula enter into the composition of its soft parts. The polypiferous 

 pinnules are secund, leaving the posterior part naked, and this is 

 marked with a deep furrow extending from one end to the other, di- 

 viding the polypidom into two symmetrical halves.

Professor E. Forbes has described this remarkable species from a 

 fine specimen intrusted to his care by Mr. MacAndrew. He says : 

 " The specimen in question is a slender, flexible rod, no less than two 

 feet six inches in length, and consists of an acutely quadrangular 

 calcareous skeleton invested with animal matter, consisting of a gene- 

 ral integument and three series of sessile but exserted polypes ar- 

 ranged unilaterally, the position of the ranges corresponding to three 

 of the angles of the stem. The animal matter in the dried state is 

 of a yellow colour and the skeleton white. It was taken both dead 

 and alive in twenty fathoms' water off the island of Kerrera near

 the recent additions to the British Fauna. Professor E. Forbes has named a beauti- 

 ful little shell Eulima MacAndrci, in acknowledgement of the services of this gentle- 

 man to Natural History (Ann. & Mag. N. Hist. xiv. p. 412), and the name must en- 

 hance the value of the species in the eyes of every genuine collector. I like these 

 names which have a " reniiniscential evocation."
