THE STRAIT OF MAGELLAN. 125 



qnently found was due to the presence of a grass of the 

 genus Hordeum; in other words, a species of wild barley. On 

 our way back to the boats a couple of guanacos were observed 

 at about 500 yards' distance, and afforded some scope for rifle- 

 practice. A very large Fuegian dog with long dark brown hair 

 was also seen wandering about, apparently perplexed by our 

 appearance. Soon after we embarked, walking waist-deep 

 into the water to reach the boat, and we got on board at three 

 P.M., soon after which one of the men brought several small 

 Crustacea which he had found adhering to a fishing line. These 

 proved to belong to the Isopodous genus Edotia, of which they 

 appear to constitute a new species, which I have named E. 

 Magellanica. Later in the day we returned to the anchorage 

 between Dungeness and Cape Virgins. 



On the 12th we continued at anchor all day, and I 

 remained on board busily occupied with the examination of 

 my zoological and botanical collections. In the morning 

 some very large simple Ascidians were taken in the dredge. 

 These belonged to the genus Cynthia, apparently forming 

 the type of a new species, which I have named C. gigantea, 

 on account of its great size — one specimen subsequently 

 obtained in Gregory Bay measuring no less than eight inches 

 from base to apertures. Upon one of these Cynthice was a 

 small pedunculated Cirriped of the genus Scalpellum. Soon 

 after this one of the ship's boys brought me a most wonderful 

 specimen in the shape of a mass of a social Tunicate, about 

 a foot and a haK long, attached to a stone. The animal-mass 

 was of a vivid scarlet colour, and consisted of hundreds of 

 animals imbedded in cells in the circumference of a fibro- 

 gelatinous matrix. I subsequently met with it in great 

 abundance in various localities in the eastern portion of the 

 Strait, as well as at the Falkland Islands ; and it appears to
