The temperature-dependent and magnetic-field-dependent ultrasonic-attenuation data of Ho-rich Er{sub 1{minus}{ital x}}Ho{sub {ital x}}Rh{sub 4}B{sub 4} polycrystalline samples indicate that the attenuation increase observed throughout the superconducting state of this system is associated with the onset and existence of superconductivity. This attenuation behavior is different from any other which has been previously associated with superconductivity, where the attenuation either starts to decrease immediately below {ital T}{sub {ital c}} or decreases after exhibiting a peak. We suggest that interaction with spin fluctuations or that perhaps a different BCS coherence factor may cause this anomalous behavior.
