adherent to the coats of the intestine, should be preserved 

 with the part to which they are attached. One of the most 

 interesting fishes of the Southern Seas is the Port Jackson 

 Shark (Cestracion Philippi). Moderate-sized specimens of 

 this species should be preserved entire ; and the head, verte- 

 bras, with the dorsal spines, viscera, and especially the im- 

 pregnated oviduct, should be preserved. The Southern Chi- 

 maera (Callorhynchus antarcticus) merits also the special at- 

 tention of the naturalist, and the same specimens of this spe- 

 cies should be preserved as of the Cestracion. 



3. HeptHes, — Specimens of turtle should be carefully exa- 

 mined for parasitic animals ; a curious Barnacle (Chelonoiba) 

 and a Leech (Hirudo branchiata) are occasionally found ad- 

 hering to these marine Reptilia. In the event of the ex- 

 pedition touching at the Galapagos Islands, specimens of Am- 

 blyrhynchus, a lizard of marine habits, should be secured, and 

 the particular locality of the capture noted. 



4. i/w/*-. — The Chionis or Sheath-bill of the Falkland 

 Islands and Cape Horn. 



The Great Penguin (Aptenodytes). 



The Penguin of the Isle San Lorenzo. 



Of these rare and desirable birds, besides the prepared 

 skins, the entire body should be preserved in spirits for ana- 

 tomical purposes. The young of the Great Penguin, and the 

 eggs at different stages of incubation, should likewise be simi- 

 larly preserved. 



5. Mammalia. — The skulls, skeletons, and viscera of a spe- 

 cimen of each species of the Cetacea of the Southern Ocean 

 are worthy of being preserved. With respect to the Sperm 

 Whale, an entire foetus, or, if of large size, the brain, eyes, 

 pharynx, larynx, and blowholes, and the viscera ; a part of 

 the impregnated uterus ; the ovaria and a portion of the mem- 

 brane of tlie foetus ; are all parts worthy of preservation. The 

 same observations apply to the great Elephant Seals (Phoca 

 Cystophora) (proboscidea) ; of which the skull and skeleton of 

 both male and female are very desirable.
