ABSTRACT
The fringed tapeworm Thysanosoma actinioides was recovered from the liver of a Najdi camel (Camelus dromedarius) slaughtered in central Saudi Arabia. T. actinioides is recorded for the first time as a parasite of old world camels.

The craniometric measurements in addition to the skull, cranial and facial indices undertaken in the immature and mature male Camelus dromedarius of the Malha phenotype (black) were: the skull length (35.99 cm), maximum width of neurocranium (11.33 cm), cranial length (15.45 cm), maximum zygomatic width (14.81 cm), viscerocranial length (20.55 cm), skull index (41.13), cranial index (73.70), facial index (72.31), cranial volume (231.73 ml) and skull weight (795.70 g) were measured in the immature camels. In the mature camels, the skulls gave the following measurements: the skull length (50.53 cm), maximum width of neurocranium (15.96 cm), cranial length (21.93 cm), maximum zygomatic width (22.75 cm), viscerocranial length (28.60 cm), skull index (45.06), cranial index (72.99), facial index (79.83), cranial volume (310.80 ml) and skull weight (2598.31 g). The results of a total of 30 skulls of immature and mature Malha camel revealed that all the measurements increased with age whereas the cranial index was the only parameter for which a decreased value was recorded. The anterior basicranial angle averaged about 203 degrees in the immature animal to increase to an insignificant value of 204 degrees in the mature camel skull. Similarly, the posterior basicranial angle did not exhibit a significant difference between the immature and mature values, which ranged between 110 and112 degrees,respectively.
