Diagnosis
ReferenceDiagnosis
E. L. Furlong 1934Merycodus hookwayi is characterized by horn-cores much heavier than in
M erycodusloxocerus or in M. furcatus. Their attitude, in relation to the orbit, is not so erect as in M. necatus or in M. furcatus, but the posterior inclination is less than in M erycodus loxocerus.
