Altar O. (Plates LXXXIV. and LXXXV.) 



Greatest length (on the ground) 7 feet. Greatest height 3 feet 5 inches. 



This altar is not mentioned by Stephens : it stands on the east side of Mound No. 7, 

 and is somwhat similar in outline to G (1) figured on Plate LIIL, with a niche cut in 

 the upper surface, but it differs from it considerably in detail. 



On the west side (Plates LXXXIV., a, and LXXXV., a) the surface is covered with 

 the semblance of a conventional plumed serpent. A double scroll (shaded) issues from 

 the open mouth ; the end of the upper jaw is turned up and forms a small grotesque 

 face, which is seen in profile. There is a plume of feathers under the chin of the 

 serpent, and from the corner of the mouth hangs a tongue which is fashioned into a 

 conventional serpent's head without a lower jaw. The usual scroll springs from the 

 back of the head. The body is clothed with scales, and ornamented with three pairs 

 of circular markings. The line of the back and the underpart of the tail is fringed 

 with feathers. Where the body begins to curl upwards the figure of a small serpent 

 occupies the corner of the stone. 



On the east side (Plates LXXXIV., b, and LXXXV., b) there are two serpents. The 

 heads are similar to that of the serpent on the east side, but they are furnished with 

 arms and claw-like hands. The bodies are more snake-like in form, and attached to the 

 tails are ornaments marked with a conventional full face, from which spring double 

 scrolls. 



Between the twisted bodies of the serpents is a detached ornament crowned with a 

 plume of feathers. 



The ends of this monument (Plate LXXXV., c & d) are somewhat worn. On 

 the north end (Plate LXXXV., c) is carved a frog and a fish, and on the south end a 

 smaller fish and two human figures. 



Stela P. (Plates LXXXVI. to LXXXIX.) 



[Compare Stephens's ' Central America,' vol. i. p. 140.] 



Height 10 feet 7 inches. Greatest breadth 2 feet 7 inches. 



This monument stands in the Western Court, near the foot of a flight of steps (Plate 1. 

 No. 15), and faces the west. The principal figure on the front (Plates LXXXVI. and 

 LXXXVII.) is in the usual conventional pose, with hands held up to the chest. The 

 face lias been mutilated. The ear-bosses are large and around them are a number of 

 ornaments, plaited ribbons, feather-work, and portions of the conventional serpents'
