nous slip, vvhich is attached to the skin of the abdomen. The lašt 

 portion arises fleshy from the tubercle of the tibia, and from the 

 peroneal /ascifl : and, covering the abdominal musdes, is attacJied 

 very firmly to the skin of the abdomen, sending ofFtvvo slips, vvhich 

 unite with their feilows over the centrai line. 



" The occipito-Jrontalis is small, arising posteriorly from \\\e pan- 

 niculus carnosus, and inserted anteriorly into the frontai bone, just 

 above its junction with the superior maxilla. The orbicularis palpe- 

 hrarum arises from the anterior part of the orbit, immediately an- 

 terior to the situation of the lachrymal bones, and is inserted into 

 the orbitar process of the temporal bone, from the inferior half of 

 which a musele arises, passing dovvnwards under the eye, and at- 

 tached to the inferior part of the o^ūc Jbr amen, sending off a slip, 

 which is attached immediately anterior and internal to the orbitar 

 process of the temporal bone. There is most motion in the inferior 

 eyelid. 



" Round the entrance of the external mentus of the ear there are 

 some muscular fibres observable, but as the part vvas much bruised, 

 1 was unable to separate them : they seem to act as a sphincter. 



" The masseter, temporalis, and pterygoideus arise as usual, as does 

 also the zygomatic. 



" On the fore part of the neck there are two museles : one arising 

 from the superior edge of \}t\Q furculum, near its union \vith the os 

 coracoides, and from the recurved portion of the coracoid bone, and 

 inserted into the temporaly«5«a ; the other arising tendinous from 

 the superior internal part o? ihe f urcnliim, and attached to the outer 

 and posterior part of the tympanic bone. 



" The tongue has a hyoglossus and lingualis, as usual. 



•' The museles of the os hyoides and lower jaw are as usual. 



" There is only one pair of museles of voice. 



" The recti postici and antici, obliqui capitis, splenii capitis et colli, 

 comp]exi, intertransver sales, interspinales, transversalis colli, spinnles 

 dorsi et colli, trapezius, cucullaris, rhomboideus, biventer cervicis, tra- 

 chelo-mastoideus, longiis colli, and scaleni museles are large and we!l 

 defined, arising and attached in the šame manner as in most short- 

 necked Birds, but especially resembling the museles of the neck of 

 the Loon; as do also the abdominal museles, and those for the mo- 

 tion of the dorsal vertebrce, ribs, and tail. 



*' The museles connecting the scapula to the trunk resemble those 

 of the Loon, but have broader attachments, in proportion as the 

 scapula of the Penguin is broader than that of the Bird referred to. 



" The principai difterences are in the museles of the vving and 

 leg. 



" The museles of the wing I shall now describe, The pectoralis 

 tnajor arises from the superior part of the crista and the external 

 part of the body of the sternum, from ihefascia of the pectoralis 

 minor, from the cartilages of the ribs, and from the anterior part 

 of the coracoid bone ; over the crista it unites with its fellow of
