 stome, whilst in H. ignicoma the basal margin is only slightly 

 sinuate. 



Note. — The shell identified by me with BiiUmus immacu- 

 latus, Reeve, seems probably not to be that species, but an 

 uncoloured variety of the Trinidad form of B. multifasciatusj

The PIano7-his regarded as identical with a Cuban species 

 should be P. terverianus^ not terversanus.

 Dr. Cunningham writes me from 



At sea, November 8, 1867. 

 (Between Monte Video and Magellan Strait.) 



My DEAR Sir, 



I have long had it in my mind to write to you, as you were 

 so good as to express a wish to hear from me occasionally during 

 my absence from the United Kingdom, when I had the plea- 

 sure of meeting you at Plymouth last year ; and I now put my 

 intention into execution. We left Plymouth on the 8th of 

 September, 1866, but encountered such a severe gale that after 

 battling with it and vainly attempting to run into Brest, we 

 were forced to return to the Sound on the 10th, and lay there 

 till the evening of the 17th, when we again set forth, and, after 

 a rather rough passage, reached Madeira, where we remained 

 for about a week. Unfortunately, we were placed in quaran- 

 tine for the first five days of our stay, so that I was not able 

 to see nearly as much of the island as I wished. So much 

 has been said of the wonderful beauty of Madeira that I will 

 not enlarge upon it, but content myself with observing that I 

 think it is about the most lovely place I have seen since I left 

 home. I accomplished a little dredging in the Bay of Funchal, 

 and obtained a variety of Mollusca, chiefly belonging to Euro- 

 pean types. A Dentalium was specially abundant in the fine 

 mud of the bottom, existing in hundreds. I, however, met Avith 

 no Crustacea. I had a delightful ride up the Grand Canal on 

 the 2nd of October; and on the evening of the same day we left 

 Madeira for St. Vincent, in the Cape Verde group. There 

 we arrived on the forenoon of the 9th, and remained four or 

 five days, in the course of which I had some pleasant rambles. 

 I need* hardly say that St. Vincent is noted for its extreme
